From Tardis Wiki, the free Doctor Who reference
The problem as I see it is that it's not quite as straightforward as you suggest, Ben More512. Doorway to Hell does not invalidate Legacy of the Daleks.
Doorway to Hell has confused matters, not made them clearer. It's provided an alternate and contradictory explanation for what happened to the Delgado Master.
I think it's still completely valid to believe that every Master depicted on TV from Terror of the Autons to Survival are the same incarnation.
Unfortunately for us, it's also possible to consider Legacy of the Daleks the "alternate" explanation, and therefore to see Delgado and Pratt/Beevers as distinct incarnations.
