Heh, O.B. now you're pulling my leg.
We're not talking Gary Edwin now, and otherwise "right-sided" is a meaningless term.
Right arm throw is either a hitter or a right-arm swinger, not Mike Austin.
He didn't specify the answer the question "Throw it around the circle? With what?"
But we can see with what in his swing sequence pictures. The right shoulder.

A left arm throw? With what? The left arm is inert. The left arm throw is a shoulder throw whether you think right or left shoulder.
You can uncock the left wrist anywhere you like as long as it's on plane and it doesn't go fully uncocked, because then you're zeroing out roll power.
May as well use a palm grip in the left hand also if you do that.
The Yoda video of going down at the plane line shows nothing of any wrist action, uncocking.

Go back and read the definition of "wrist throw". It's a release trigger, not a power source.
And it has to be planned no later than Top on the downswing.

Mike Austin used a Shoulder Throw, with (right) wrist throw, non-automatic because of conscious effort to start the roll before the end of the hands' path by straightening the right arm. And that has to be started or planned for well in advance of the actual action. Whether he actually used it for additional power is moot, i.e. pushing on the inert left arm.
Furthermore, if you're not close enough to the ball so that you still have enough right arm bend to get through impact and low-point, you run out of right arm and inevitable clubhead throwaway.

Get the right shoulder Down, preferably on plane.
