Comment 1 for bug 564568

It's probably because the file-id of the tree-root is different in the two branches, so from bzr's perspective they are in a different directory that happens to have the same path.

I agree this looks pretty confusing, so we should try to figure out a better way to explain this situation in the status output.

Separately, this isn't a situation that is likely happen very often so I wonder how it happened to you?
