don’t know the yellow book well enough to know if this is totally TGM compliant, but here is how i view swinging vs. hitting:

first, i think it is helpful to look at the motion at shoulder level…so, grab a club and set up…then bring the club up to shoulder level and make your stroke…if you swing, at some point your trail hand should rotate to be palm skyward with the clubshaft and clubhead still roughly parallel to the plane of the shoulders…the butt end will be the closet part of the club to the “ball” and is the part you pull back toward the “ball” until release when the palm rotates back from skyward (parallel to the plane) to targetward (roughly perpendicular to the plane) and the clubface to the “ball”…if you hit, you keep the trail palm facing the “ball” and rotate the clubshaft and clubhead (around PP#1) to be roughly perpendicular to the plane of the shoulders and PP#1 is what you push back to the “ball” until release rotates the clubshaft and clubhead back to parallel to the plane and to the “ball”

You have described the Swinger's Standard Wrist Action (10-18-A) and its Sequenced Release (4-D-0)which requires the Left palm to be Swivelled On Plane during Start Up. It remains On Plane with the palm riding the wheel rim until the Release Swivel takes place, rotating the Shaft back on to its own Plane, ready to apply the selected Hinge Action (usually Dual Horizontal).

The Hitter has identical Left Hand to the Plane relationship as the Swinger at the Top, however it got there in a different manner. Instead of a abrubt Start Up Swivel, a Hitter turns his Left Wrist gradually just like an Angled Hinging motion. And so it comes back down into Release in the same way, a Simulataneous Release Motion.
