(b) No runners advance on the misplay..."

Obviously, "errs" in this situation does not mean the ball went out of play.

Getting back to the other part of my OP, in NCAA is the appeal of R2 permitted or not (regardless of whether it is upheld or not), even though the defense was wrong on R3?

Yes, err certainly does not mean is incorrect about leaving early.
