It's sad when you respond to your own post, but it occurred to me that if you can do the 90-degree shoulder thing so that there is minimal twist in your wrists at the top of your backswing, by delaying your release (leaving the club cocked well into the down swing) your wrists are forced to lag behind your shoulders that are rotating back to square during the downswing until centrifugal force straightens the club out and you can roll your wrists (and the club) back to square just before impact, which you can only do with your arms/club fairly straight (the rotational moment of inertia thing). If you do the combo swing you are probably doing the same thing except you start your backswing with your wrists slightly twisted. Where in your downswing you roll the club face square depends on where you 'release' the club. A late release means a late roll.
I think.
Regards again
