Leo,
I've had similar experiences with some of my students, especially the poorer players, if they get too far across the line with the right elbow too far away from the ribcage, they don't seem to be able to get it back on the body fast enough and the result is a very steep start-down which requires an early lift of the left shoulder to get it back on plane and often an overcompensation leading to pushes and hooks depending on the face. In this sequence of John Daly you can see how the shaft is above the seam of the right shoulder. I've noticed that Brian's shaft is sometimes in the same spot.
It gives them too much work in too short a period of time, it seems to me.
