You ask how JS hits the ball high with only a 4-6 degree driver loft and a descending clubhead path pre-impact?
Good question.
Maybe that forward kick of the shaft is "real" and not due to camera artifact.
If you go to nmgolfers website at http://nmgolfscience.tripod.com you will find a 200 page research paper called "Role of Shaft Stiffness" by Sasho MacKenzie. Interestingly, it demonstrates that many golfers may have 5cm of lead deflection of the clubhead at impact.
Here is a diagram from that research paper that shows how dynamic loft changes with lead or toe deflection.
It shows that dynamic loft increases by 0.8 degrees for every 1cm of lead deflection. That means that 5cm of lead deflection would increase dynamic loft by 4 degrees.
