Aha! I stumbled over that too a few weeks ago. Regardless of the glacial pace and rambling repetition, there's actually some good insight.
The key point being that (he claims):
Max writes entire melodies first, before anything else.
I took this to mean (if true) that Max will just think of a good melody, THEN add the chords and production, and finally the lyrics. The more I thought about that the more it made sense, since then your melodies aren't boxed in by a backing track. I've tried to do it this way a few times since, and it definitely works... also I dont sing them into my phone til I've completed a whole section. This way FORCES you to write memorable melodies, coz if you can't remember each distinct phrase for a few minutes while you're working on the other phrases, then it's not good enough.
Not sure where he got his info though, from everything I've personally read I got the impression that Max would write melodies to track. Anyone?
