A Swing Stroke Pattern would move the SS away from the ball then align it with the club shaft plane as PP3 rotates under the shaft. At release position the SSP is now above the shaft and as the shaft rotates around the SSP returns to impact. Hitter never rotated it.
see Hand Action.
In the backswing I think it is better to move the clubhead/sweetspot around the hands and clubshaft, not viceversa. Because in the backswing anybody cannot generate so much centrifugal to mantain the lever's center of gravity (sweetspot) in a constant angular motion (flat, 2 dimensional circular path) while applying other not on plane forces such as turning, hand motion.
You turn your hands, the clubhead moves more inward, but the hands don't move out, If the turn is made strongly.
However, in release, you can try roll the hands(a swivel at impact, just for the experiment, because hinge action gives more precision). Sweetspot always stays on plane (for example the square shoulder plane), the hands rotate/move around it. So clubshaft/left arm come to near to the ground and closer to the body.
I remember reading on a chapter that the clubshaft moves around the sweetspot. I think Homer Kelley was referring only to the downswing.
