If there is any serious acceleration going on during the release interval, the hands and sweet spot has to move towards a common plane.

Hogan wished he had three right hands so it goes without saying that he didn't purely drag the club through impact. He must have been applying a lot of pp#1/#3 through the ball. As far as Luke Donald is concerned, throwing is a very ambiguous term the way you use it to describe Donald's release & impact but no matter how I twist the meaning of the term, throwing plus raising the head before impact doesn't make any sense to me whatsoever.

There is a distinction between the 3-d path the hands move through and where the line between PP#3 and the Sweetspot is tracing. For example in the Turning Shoulder Case(pg 156 - 6th ed) - the Arms hang at Address and take over the vertical element--pointing at and along a line on the ground parallel to the Target Line(not on it). So the hand path and sweet spot don't have to move toward a common plane.

Yes he did - the pressure he felt at PP#3 was lag pressure - a "receiving" pressure. He was pulling all the way in what Morad calls a "cp" swing, in which the lag pressure is felt to pull toward the body mass center. Notice how bent his right arm is through Impact. Donald uses the Morad and TGM "cf" Swing, in which the hands are thrown away from the flywheel - the Right Shoulder. His head raises up to counterbalance the hands moving away.
