Well, it should work like this: once the parser decides that a query
looks good, it seaches for the catalogue to find out all the names of
implied relations. Therefore, the binding you mention should happen as
late as possible. However, I'm not sure if there a kind of caching
mechanism that can invalidate such sentence. Someone with more
experience can detail better.
