Opposing coach approached Plate Umpire between innings to change pitchers. The "new" pitcher has thrown a single warm up pitch when the coach "changes his mind" and wants to return to the "prior" pitcher and not make the substitution at all.

So - my takeaway from the discussion of this situation is that the player is in the game (substitution is official), but does not have to pitch.
