Yeah, I'd assume you wouldn't be hitting a max until the end. The more I train the more I believe this type of programming is the way to go, lots of volume at submaximal weights. Gets you strong with less risk of injury.
I've really enjoyed it. Like Doc always reminds me it's not built to make you fail but it's definitely not build to be easy either. I've struggle a bit I think because there have been a few movements that I've never done before and jumping into them with 60-85% max for reps was an awakening. Plus it's got some crazy volume as well.
