It's sad that even in an interview like that, he isn't able to be sincere when describing the writing process of what is essentially a simple fantasy movie. Instead he needs to burp his programmed "Lucasfilm mythology." The expression on Nolan's face is basically "What the hell are you talking about."
I read no such expression on Nolan's face, although I will concede that I'm perhaps not as familiar with it (his face, that is) as you may be.
