I'm not sure I would accept the coach's question as a valid appeal.

It sounds as if he's not sure and he wants to know what I saw. If I tell him that the runner did not touch the plate, have I coached the coach?

I need to hear from him that he definitely thinks the runner did not touch the plate and he is appealing that. I can also allow for the fact that I would consider his voice inflection and body language in him asking the question to make it a valid appeal.
