So my understanding is he believes math is invented, and exists in a "neo-fictional" space where things can be both true and false. Because if it were pure fiction like Star Trek then Math's statements would be false. To me this seems a bit off, but I'll assume that it's my understanding of what he is trying to say that is flawed. Also, didn't we all use the unit circle in Calc?
