Well, pivot is a word that covers the entire move back and forth, including the lateral and rotation, also tilts. What i meant was, if he was hitting it fat, and was confident that his left wrist was flat, the issue wasn't throwaway as much as the right shoulder going down(axis tilt) AND forward(rotation), which also helps send the club down and forward to low point(past the ball).
I was tired and tried to get away with a short reply, sorry
