Speaking purely as a user, I think a case can be made that it really is
different. We could say:
If the file exists, auto-revert updates the buffer based on its
(possibly empty) contents. If the file no longer exists, then there
is nothing for auto-revert to do, so it does not modify the buffer.
However, Michael mentioned in a previous message that the buffer would
also be left non-empty if the file existed but was empty:

That seems less conceptually clear to me, though I can imagine
cases where it would be more convenient.
