If I recall correctly, he's concerned with what you need to wear when running to win a 100 mile ultra. Minimalist shoes don't force you to land lightly--at least not enough. Wearing them takes a great deal of self control. Using feedback alone in those first comfortable hours is not sufficient to prevent you from slowing down a great deal due to tender feet later in the race. Without sufficient protection from rocks and roots you won't be able to run at all close to your best pace.
I've learned the hard way. Unless I can train on the course, I'm going to err on the side of caution from now on and wear something with a fairly thick sole. After training hard for a race and paying for registration and travel, finishing poorly or dropping out due to footwear isn't very much fun.
