How do I update a working tree to an old revision?

Ok, I agree we should have 'bzr update -r', but yet, I don't see
what is wrong here if you have one branch somewhere that you
refer to from your local working tree, branch:

bzr branch <trunk> work
cd work
bzr pull --overwrite -r <revno>
test, that works
bzr pull --overwrite -r <another-revno> 
test, that fails
bzr pull --overwrite -r <yet-another-revno> 

The revnos used by pull refers to <trunk> not your local branch,
so it doesn't matter if the local tip is changed.

What's the problem here ? Do you use a setup I don't understand
that makes the above impossible ?
