Ernie Els is a great Swinger, but
not a Right Arm Swinger. His Stroke Center is the Left Shoulder which gives a much longer Swing Radius.
Why is Els not a Right Arm Swinger? Because his Stroke Center is not the Right Elbow! So
by definition he isn't a Right Arm Swinger.

Anyone who thinks his Stroke Center is the Right Elbow, please put your hand up!
Anyone who didn't raise their hand, and
still thinks Els is using a Right Arm Swing --
you don't know what's a Right Arm Swing!
