There is no reference to his diagram being 3-D and his arguments about levers which the diagram represents) are 2D arguments and do not address axial rotation of part of the lever system.
"Around July 15, while working with the device, I made a different motion from the top of the backstroke. I moved the right hand directly away form my body instead of down. There was an instantaneous explosion of club head speed and accuracy. The ball flew almost twice as high as my normal wedge and had the same distance."
You seem to draw the implication that the 'normal' wedge referenced in this sentence is without the trainer. Such an implication would suggest that all wedges with the trainer went twice as high and that is clearly not what is meant in the statement. He is saying that the change in motion (while still using the trainer) resulted in the changed flight (vs the previous motion with the trainer) and twice as high with the same distance implies higher effective loft at impact. That means the clubs relationship to the lead arm was not held fixed by the trainer.
