If two or more expectations come from the same master, the returned expectation may not be the one that user-space is requesting. This is how it works for the expect deletion operation. Although I think that nobody has been seriously using this. We accept both possibilities, using the expect tuple if possible. I decided to do it like this to avoid breaking backward compatibility.
