I think so too.  The support for position() is a bit ad hoc.  The
support for last() is even worse, because it makes good performance
difficult.

It doesn't help that the XQuery documents are inconsistent as to the
semantics of position().  (Is it "lexically scoped", as implied by the
formal semantics, or "dynamically scoped", as implied by the other
documents?  I haven't managed to get an answer on this fundamental
question.)
