For simplicity (now ain’t that an oxy-moron on this site!) lets envision a golfer at “address”, zero accumulator #3, FLV left “wrist”. So clubshaft and left forearm in a straight line resting on an inclined plane. An awful lot like 1-L. For purposes of this discussion, lets not quibble over clubshaft vs sweetspot planes, impact vs lowpoint plane lines, etc (unless of course this causes me to draw incorrect conclusions)

For a RIGHT-handed golfer, the RIGHT forearm and clubshaft rest on the inclined plane. Hence, "the magic of the RIGHT forearm".
