What Am I Missing?

[Snocatzdad]

What if the illegal pitch ruling precedes the left early in the following manner

Pitcher does two windmills (runner leaves on what they thought was release on first windmill ASA 6.3.D) In that case the illegal pitch causes them to leave early and I believe it would be correct to allow the offense to choose the results of the play.

I guess the crux is that it's likely for the pitch to be illegal before release so it's possible that the infraction on the pitch is prior to the infraction on the base.

I would think minimally you would allow the offense to choose the result of the play or a ball and runners advance. With that result being that you called the runner on base out for leaving early and they probably wouldn't want to keep that result and would take the ball and advancement.
