if you go to "end"...you come back via "top"...HK describes this as "top arc" and the circle delivery path as an extendsion of this "Top arc" path...there is no axis tilt in a circle delivery path so I presume there is no axis tilt in "top Arc"....there is no early axis tilt to give early straight line delivery path.
Why don't you try and do some straight line thrusting yourself....vary your aiming point....see what shapes you get.... ?? Less gendanken...more ge-do-ing...
Most of the axis tilt in Hogan's swing came later in the downswing.
For your own experiments - you only need to go to shoulder high backswing , you can draw a straight line....don't be scared...do it and post your own stuff....then ask why does it work / not work....BH has never committed to paper of public record that he had an aiming point concept outside his experience of PP3 through the impact interval (as per Coleman video)...It is less than fruitful to interpret his swing through the medium of a concept which he almost certainly did not use consciously. But you on the other hand know all about it....
I have spent many, many hours playing with the aiming point concept. I don't believe that is has a major effect on a golfer's ability produce a straight line versus non-straight line hand delivery path in the early downswing.
I think that the straight line thrust is mainly useful for sensing/maintaining clubhead lag and it may/may not affect the release point of PA#2.

Jeff, downswing waggle, aiming point, delivery path, plane shift - they are all linked together...where is your data from all your hours playing...what are you basing your conclusions on...."feels as if"? Surely some of those hours playing with these concepts have been caught on video at the very least?
I would love to see 3D data - with trackman if you have it - of a player using aiming point concept, various aiming points....see what happens...if you really want to know this stuff then you have to try it with feedback.... convert some of those hours into dollars (time is money) and rent some trackman time... I'm sure the custom fitting guys are feeling the credit crunch and would love to rent you the T-man for a few hours.... it's not like they'll be selling many clubs at the moment!
THEN post your data using aiming concept rather than Hogan data when he almost certainly wasn't using it.
You state the hand delivery path is down-and-out-and-forwards. However, that only applies to the second half of the early-mid downswing. In the early downswing, the hand delivery path is down-and-out-and-backwards - as can be seen in this photo of Hogan's swing.
Note the direction of arrow number 1 - it is slightly backwards (away from the target), and not forwards.

Congratulations on another good question with photographic evidence. You have clearly shown the hands moving backwards from the top but in 2-C-0 Homer refers to the Three Dimensional Downstroke as being, Downward, Outward and Forward. In the photos 9-2-6 (Top) and 9-2-7 (Start down) he also has demonstrated the backward movement of the hands but from 9-2-8 (Downstroke) the hands move forward as he claims and that tallies with your second arrow and the points you have made. It hinges on the definition of ‘Downstroke’. There are many misinterpretations but as usual using Homer’s definitions, he was correct.

Just off the lesson tee. Looks like some good points being made. I especially like the Delivery Path visuals.
One quick point, Jeff . . .
Aren't Photos #2 and #3 out of sequence?
Oh, I see now . . .
You apparently didn't mean them to be in sequence (they are in pairs).
Strav - you are correct that the downstroke 9-2-8 only starts from the mid-downswing. However, the hand movement in a full golf swing starts from the top (or end) of the backswing.
If people use the aiming point concept from the mid-downswing (official start of the downstroke of 9-2-8 ) then I can clearly see how one can use the aiming point technique to aim the straight line thrust at the ball. However, I cannot envisage using the straight line thrust action from the end of the backswing position where the clubshaft is parallel to the ball-target line and PP#3 is under the shaft.
I also do not understand what a straight line thrust really means for a swinger. A swinger should only experience enough pressure at PP#3 to sense/control clubhead lag because he is not drive loading the club.
I still have not seen anyone present any evidence that this straight line thrust action affects the hand delivery path - turning a circle delivery path to a straight line delivery path. Yoda stated that this "straight line thrust action" is used in all hand delivery actions (10-23-A or 10-23-E).
GBD - see my comments in the hand delivery path thread.
