3putt,

Here's my simple view of this. It is clear from the drawings in 2C that the ball rotates during contact. It is a physical fact that this rotation will proceed until the ball is exposed to a force that stops the rotation. I can't see any force present that would do work the ball clock wise here and stop the side spin. Except perhaps the wind drag that will reduce this minute sidespin during the air time.

I think Daryl's quote must be read in the context of the relationship between centrifugal force and inertia. When the ball leaves the club, the centrifugal force is shut down and the ball proceeds in the direction it had at separation. I don't think that quote is ment to address side spin.
