Hinging is simply remaining perpendicular to one of the three basic planes (vertical, angled, or horizontal). There is no 'independent' roll.
Swivel IS an independent roll outside of the selected hinge action. Through impact the roll is simply the hinge (this is NOT swiveling), then as the clubhead goes past the hands the left wrist is forced to swivel back up the plane and everything else doesn't keep up. This independent-of-everything-else roll is swivel.
I personally think way too much is made of swiveling. Unless you're chicken-winging after impact, you're swiveling.
Matt knows his stuff in case anyone didn’t notice. Much is made of this geometric on-plane safety valve. But we all learned it at one point or another, so here goes....
Few points on swivel.
Swivel is not a segment of any hinge action. Hinge Action is a non-swivel action.
Swivel is also independent of the forearms final roll after impact, although with a true swinger the long smooth turn (to right) and roll (back to left) of the hands we blend the swivel seamlessly.
Swivel is more “active”immediately after impact in a Swing stroke and less active and occurs later in the Hit stroke.
So what is it? I like to think of the swivel in a Swing Stroke Pattern as a safely valve to allow the left wrist to remain flat and prevent any throw-away that centrifugal force is pressing to achieve and to allow the club to stay on plane into the follow through.
The swivel action occurs after impact, after the hinge motion and is a slight subtle turn to the left of the flat straight wrist. Remember, it is the left wrist that controls the clubface in the hinge action and the right hand controls the clubhead. Left is passive and the right is power. However with the swivel, the left wrist is more active than it was applying the hinge action. Without the swivel the club would have no chance being on plane into the follow through and without it the swing would end awkward. .
