Take John Frobisher and Maxil, they look like the Doctor but that's a biological thing, they weren't created for that purpose.

Where as Robot Doctor amongst others were created to serve the purpose of being them and made to look like them. It'd seperate a tricky category and make it easier to understand, rather than having to work it out for one's self.
