Legal pitch?

By the description, it seems to me that there isn't a second revolution, which would of couse be illegal.

You may be right, but Kent said...

Here the ball is released to the batter early in the free foot stride, well before the free foot plant. The pitcher then continues her windmill like normal (but ofcourse the ball is already gone).

I visualized "early in the stride" to be before the windmill motion, and "continues her windmill" to mean a full rotation after the ball is released.

The pitch you are describing is the so-called "sling shot" motion, and you are right, it is perfectly legal, and can be a very deceptive changeup when mixed in with the windmill motion. The key is the pitcher cannot make another revolution (i.e. go past 12:00) after releasing the ball.
