There is less roll to a horizontal hinge than most might think. The easiest check is to go to the horizontal plane.

At any point in the motion from hip to hip, if you raise the club up to the horizontal plane, the toe should be straight up.

the closing motion, relative to the left shoulder hinge pin, is exactly like a closing door, and a closing door has a smooth, steady rate of closing. It may feel like a quick roll with a snap release down on the angled plane, but the hinge motion - from impact to separation - is as smoothly closing as that door.

Part of the advantage of the pivot causing the throw out and roll is that the pivot acts like the rotor that the door closes around - a smooth rate of closing. Not a swivel as hinge action.
