No he's not. Go back and watch it again. The Time Lord says that there are 13 of them, he doesn't say anything about numeration or about the 12th Doctor.
I agree, the line has potential ambiguities, but myself I think it states a plain case. Thirteen Doctors = thirteen Doctors, and the line is
said when Capaldi makes his entrance.
But anyway, the point is moot. As has been said, the showrunner decides how these Doctors are supposed to be referred to, and whatever is decided is fine with me.
Totally agreed. If there are now 13 official Doctors, and like I say that seems to be the thematic thrust of the story, and if it is the intention then I welcome it with open arms.
