No problem if that's what you are saying. But it seems to me that the Swivel is a Swivel whether you purposely do it, or it gets done by the orbiting of the tension free arms. It's still a Turning and Rolling, whether a deliberate action or a result of another action.

As long as you understand the difference, that's the important thing. But please...

Tell me you understand that the 'Roll' of Horizontal Hinging -- with the Flat Left Wrist remaining perpendicular to the ground (horizontal plane) -- is not a Swivel.
