I would disagree.

Once a runner legally attains a base, and the pitcher subsequently delivers a pitch (or even engages the rubber with possession of the ball in preparation to make a subsequent pitch), the runner may NOT retreat to a previous base for any reason. (7.01 Comment).

I agree with mbyron's assertion.

Rule 7.01 Comment: If a runner legally acquires title to a base, and the pitcher assumes his pitching position, the runner may not return to a previously occupied base.

In the OP, the pitcher had not assumed his pitching position when the runner retreated.

Bob - if you quoted that rule without referring to your baseball books, I am truly impressed.
