Not necessarily true.

What makes you say that? What motivating force are the magnetos providing
that keep the engine windmilling with just the mixture cut off, and which is
absent when you ground the mags?

Windmilling? I took you to mean that the engine that continued to run with the
mixture at cutoff would also continue to run with the mags off.

Yes, if it's windmilling at idle cutoff it'll windmill with the mags off.
