The extensor action and the right elbow location are two completely separate issues. Extensor action is the right arm always trying to straighten against the leash or checkrein of the left arm. That means the further the right hand goes toward the right shoulder it will bend. If you draw a straight line from the shoulder to the base of your right hand, the bent right arm could theoretically without regard to anatomical constraints could rotate around this line and effect the elbow location without affecting the extensor action for any given point.

If you simply keep the left arm straight, then bend the right elbow, the right hand moves closer to the right shoulder. So what? That's not theoretical.

If you move the right elbow out away from the body during EA RFT Start-up and Backswing, then you're just struggling and more theory won't bring you any closer to applying the Magic of the Right Forearm and its perfect motion geometry. EA Backswing and EA Downswing, are related because the left arm is a checkrein in both directions. Checkrein is just step one. EA is an action permitting not causing. The Straight left arm is a checkrein against the straightening of the right arm on the downswing, and against the bending of the right arm during the Backswing. EA will allow you to easily acquire the flying wedges and the longitudinal alignment of the left arm and clubshaft as long as you don't muck it up by forcing the right elbow out of position that EA created for it. That's not theoretical. IMHO.
