It's not inaccurate. Just because you turn turn insane due to it does not mean you turn into a different incarnation. Simm's version was vastly different between Series 3 finale, Series 4 special and Series 10 finale, but he was all the same incarnation. This scenario is exactly the same, but with two different versions of the Master.
