I agree that there are a lot of factors involved in PA#3 rollover, but I don't think that is requires conscious action to control these factors because they occur naturally. I have previously mentioned two factors that affect the PA#3 rollover action. 1) The on-plane movement of the right forearm pre-impact which causes the right palm to face the target by impact and 2) the physics of the clubhead/clubshaft which causes the clubhead to roll over naturally during the release phase.

Consider a third factor. If a swinger performs a right forearm takeaway action the right hand gets to the end-backswing position and ends up like a waiter holding a tray of dishes. The left hand has to follow the right hand because they are conjoined at the grip. If one keeps the left arm straight and prevents the left wrist from bending, then the left arm is obliged to rotate clockwise during the backswing - so that the watchface on the left wrist, which faced the target at address, faces slightly skywards at the end-backswing position. During the downswing, when the shoulders rotate to a position that is parallel to the target line, or slightly open to the target line, then the left arm will have a natural/automatic tendency to rotate counterclockwise to its resting state (the back of the left hand will face the target when the left arm hangs down naturally from the shoulder). In other words, release of PA#3 (roll over of the left hand) occurs naturally if you do not interfere with its natural action, and it does not require conscious thought. One merely has to ensure that the right forearm is on-plane pre-impact, so that the right palm progressively faces the target as it reaches the impact zone. The combination of these three factors will allow the the left hand to roll-over naturally without any need for conscious thought.
