Jeff,
Before I briefly answer your question, let me say I really don't have a lot of desire to hash through golfing machine information in detail. Therefore, while you may have many, many additional questions- if so- someone else can jump in and answer them. 1) I certainly wouldn't want to ignore future questions without some explanation and 2) right arm swingers are few and far between and to me appear to be compensated procedures- so it's a very small world and although good to know the essential characteristics - not one to spend a lot of time on, in my opinion.

If you are a swinger you pull the club.
A right arm swinger would be primarily pulling with the right arm or musculature that supports the right arm acceleration.
A left arm swinger would be primarily pulling with the left arm or musculature that supports the left arm acceleration.
(Not that there wouldn't be a full body feel and many things pulling- but that would be the general distinction between the two. It certainly wouldn't mean that you would only feel the left arm swing ala Leslie King or only feel the right arm swinging.)
Now, If you are pulling with the right arm- then inherit in that action is that the "center" of the swing moves to the right elbow according to Homer Kelley (see 10-3-K 6th edition). Imagine the shaft primarily rotating around or oriented to the right elbow due to the physics involved. If pulling with the left - the "center" of rotaton is the left shoulder. Essentially imagine that the shaft rotates around the left hand and the left shoulder.

So for the golfer on the video- A) it's obvious to me that he is pulling i.e. swinging versus hitting and B) notice the "hang back" or the center of rotation around the right elbow. When I say "hang back" - I really mean that the right arm swing creates certain pivot and body motions that appear different than a "normal" left arm swinger- which kind of highlights the effects of the method through the resulting body motion. Less posting up on the left side etc.

It's not that he should become one so much, but more that he is a right arm swinger and he should "maybe" understand it so that he can be aware of his procedure so that he can be consistent with it and understand the pattern- what works with it and what works against it.
