Hanover Square / Tenterden St behind Oxford St / Oxford Circus is the
eastern exit point for Bond St Station. IIRC there is no physical link
to Oxford Circus tube station. Only in London could we fail to provide
such a link.

Perhaps a "crowd control" feature. They want to spread the people out by
making them take a roundabout route.
