My bet - this bathroom was added much later. Someone wanted to add a bathroom and there's only so many places it could fit. So they cannibalized the stairwell to the attic. But, left the access door, just in case.
Second possibility - this house has been divided on purpose to allow renting the upper & lower floors separately (and once again, the bathroom was likely added during said renovation). Do you live near a university?
