Disjoint is also true for subdirectories that are a working copy of their own. The requirement is that the directory is recorded as subdirectory in the parent directory. (The url can be switched, from a completely different repository.. or just like that of a normal child, but unconnected).
(With access batons you also have the case that the access baton for a directory is just not open, so you can't step inside)
I don't think the current wc_db public api allows to differentiate between connected children and children obstructed by a different working copy. The entry based api can, via the stubs handling. (Just walking the children will just show the node from the child working copy; obstructing access to the information in the parent).
I think we need a new wc_db api to help detecting this case. (It should check the current_relpath from the pdh search operation. If it is "" then it should check if the node is connected to the parent directory or not. This way, once we move to a single db per working copy, we only perform this check for roots)
