I have seen where this is only happening on the tee. Then during front toss the shoulders don't over rotate like seen in the tee clip.
Bat is wrapped to much due to the over rotated shoulders.
I've seen this, too. A ball on a tee, the hitter can over-rotate and still see the ball. With a pitched/front-tossed ball, over-rotation will make them lose sight of the ball. One approach I've used is to get them to look at an imaginary pitcher during the early part of the swing process, and track the imaginary pitch to contact.
