You have gotten the real deal from the knowlegeable above, but I saw something at the range earlier which reminded me of your question.
Check that you are fully committing your right shoulder downPLANE.
The guy at the range was doing what you pointed out. Pulling, then Hitting at the bottom. It looked somewhat OK from the 10-5-A visual "angle", but when I moved over to 10-5-E visual "angle", his shoulder was above plane.
An early right arm thrust just added to his woes as the clubface layed back. From that shoulder alignment his Angle of Attack was steep (or is it Approach, I get the visual equivs mixed). It was decidedly worse with the longer clubs.
A number of problems seemed to solve themselves when he did drive the right shoulder with full intention.
