I asked during a webinar about this (and thought I was told it was auto-sensing).
It seems to me the PoE output on an R200P or C3VoIP-200P may be always on. My Mikrotik just has a small seizure when I plugged an R200P WAN port into it for configuration. My volt meter shows 29.8V on the open port. These scenarios could be triggering the auto-sense, but I want to check:
Is the PoE output always on?
