It's about getting your nervous system prepared for a heavy load. If you just say, warmed up with a high set of 8 at 225, you're going to get crushed when you do your max.
I can't speak for the sets from 405-445, but the idea is correct. You'd probably want to ask on a powerlifting forum though for a better idea of what the sets should be (Itlan could be right though).
