There are situations that aren't solvable (because of different language files), so if the user really wants to have duplicated name, allow him to do so. It solves desyncs between server and clients using different languages. It behaves the same in SP and MP, so users won't see the different behaviour as a bug (and even checking in SP could be worked around by the user).
