Nope, it looks the same to me and I have a screen with high contrast and high brightness. Both his examples are very hard to read. And I have done color blindness tests and know I am not color blind.

Another thing: I think one thing he is missing is how important it is to see at a glance where function definitions are and where possible early returns are. The first example highlights def (function definitions), return (possible early return) and the return type (arguably not that important in most cases).
