Yes, I have found this to be helpful as well. It helps me to visualize and rehearse the following:

Horizontal Hinging:
Toe Up on both sides of the ball when the club is parallel to the ground and the target line (swing Toe Up to Toe Up). This is a "full roll" feel.

Angled Hinging:
Instead of toe up to toe up, I visualize the leading edge of the clubface to be parallel to my spine angle halfway back and halfway through. Angled hinging is synonymous with that "no roll" feel that you are getting.

Vertical Hinging:
Leading edge pointing to the ground in the backswing, leading edge pointing at the sky when the club is parallel to the ground and the target line. The only way to accomplish this is to have a "reverse roll" feel.
