Here's my best educated guess since I've never experienced it.

Based on what I've read, the Golfers Elbow condition is due to aggravated over-use of a forearm/wrist motion; either right wrist bending forward and/or forearm rotation similar to a Tennis Topspin swing motion.

Both of these motions can happen in a RAS swing if the right forearm and elbow (swing center arc) are forcefully rolling through impact, then the clubshaft is snapped inline with the right forearm during follow through. I think this would have to be an intentional motion on the golfers part to try and manipulate the clubface with the right hand.

If the RASer allows Centrifugal Force and the left wrist to manage clubface alignments, perhaps this is easier on the ligaments. The clubshaft will still align itself with the right forearm during follow through because the right elbow is the swing arc center.

Again, this is my best guess. Maybe others who have experienced this condition can chime in.
