Is this method of sidesaddle putting anchoring?

[JerseyThursday]

I was looking at a site where this guy makes custom sidesaddle putters. In his description of how to use this technique, he states: “...the left hand is simply a stabilizing factor while the left arm rests on the left side of the players abdomen.”

Is that considered anchoring?

By this diagram I would say no. It doesn't look like you are anchoring your left hand/forearm too your chest.

In looking at that diagram, under “prohibited” it states you cannot create an anchor to your side with your forearm, yet it’s ok to anchor with the elbow and biceps?

If that is what the USGA has said then yes. You can keep your bicep and elbow against your side. You can not anchor your forearm against your body.

Anchoring your forearm takes the elbow hinge out of the equation. 

Anchoring your bicep still leaves the elbow joint free.
