I thought the same. But then I thought that a supervisor is probably going to understand even less than the teacher, which just biases them even more to siding with the teacher. It's hard enough to get people on your side when they don't understand what you know; it's even harder when they don't even understand how you could possibly understand. That said I don't think he couldn't have done better. I don't think I'd have done the tedium of commenting every line of code; I'd rather write a script that just parsed out the doc of every function call and pasted it next to the function call.
