That is odd.

I would think it would work as you expect. I suspect the problem has
something to do with what is called "cross-site request forgery"
(CSRF). The technique for combatting that requires that you *start*
by entering the appropriate page, which provides a digitally signed
one-time authorization token, which expires after a fairly short
period. You then send the token back when you fill in the form, thus
proving that you've followed the correct procedure. I suspect absence
of a token is being treated the same as an expired token. I hope it's
a bug and can be fixed, but I don't know much about that part.
Hopefully Mark has an answer to this one.
