Scrooge's explanation here is quite succinct. I find myself drawing parallels to a joking suggestion I once saw that any story that contradicts An Unearthly Child in any way whatsoever must take place in an alternate universe.

The second film took a perfectly logical approach as I see it. The DWU was still young when it was released but it had expanded since the release of the first film. The prime pieces of media I can think of being "A Battle of Wits" and "Checkmate" establishing that another of the Doctor's race also had his own TARDIS which cast doubt over the Doctor's claims in The Chase that he invented his ship.

By not mentioning Dr Who's race, the second film remained wholly faithful to both the DWU at the time and Dr. Who and the Daleks. The second film could be watched alongside the first one with nothing lost (as with the Into the Dalek example above) but equally somebody tuning in to the film in isolation, with their newfound Who knowledge from 1966, would not find any contradictions with established lore. A perfect compromise to please both groups as I see it.
