I think its another definition thing again. To get Homer you gotta get his point of view I believe, his perspective , eye ball wise. DTL, caddy, players view etc. D sorted me out on one of these a couple of months ago as I recall. Its easy to get things mixed up. Homer can also, in words, shift his visual point of view quickly. Angle of Attack, Arc of Approach......different points of view of the same clubhead path. Confusing but very necessary.




"At right angles to the spine" here to me implying looking DTL at a golfer, who given waste bend will show his shoulders describing a motion which is at right angles to his spine but tilted forward vis a vis the ground. Like Mr Woods in that photo above say.

I am comfortable with HK's view. This should be easy geometry. The component- Shoulder turn, The variations- HK illustrates 5,
lets reduce it to 3. We place a disk centered at the golfers axis of rotation. put a point on the circumferance of the disk.

#1 the axis and disk are not rotated- Varation ZERO
#2 The disk and axis are rotated such that the disk plane is always perpendicular to the axis of rotation- variation ROTATED
#3 The disk plane is not perpendicular to the axis and therefore the disk will appear to "wobble" on the axis as the disk and axis are rotated. This is the variation that exists for "flat" backstroke and "on plane" downstroke or other planes that dont meet #1 or #2.
There is more geometry. If, the DS plane Top is not precisely located for a proper "wobble" the golfer can not obtain/maintain a straight plane line without compensations. This "wobble is set BOTH by amount of backstroke rotation and axis tilt at/near the top.

Just my opinion-All disclaimers apply

Ps. Which leads to the question - Should the shoulder be on a downstroke plane to the plane line or to support the hands?
