Maybe because you're still using Emacs-22?
This part of the code has been changed in Emacs-23, and in my tests it
seems to do what you want.

PS: Note that this `predicate' argument is not handled quite right
currently, because it doesn't distinguish between "intermediate
completions to accept" and "final values to accept". So if you want to
be able to complete "/u" to "/usr/", then you need to accept "/usr/" as
a valid candidate, even though you only wanted to allow this completion
to let the user complete its way to a .pdf file somewhere underneath
/usr.
