I don't think he formally uses big-O but understands if something he is writing is linear (iterating over an array), exponential or O(1).
People have to get rid of their big hard on for Big-O, a useful concept that takes a couple hours to learn. It isn't a difficult thing that only the true macho programmers can know. I'd wish it was traditionally in starting programming books in the 'optimization & profiling' chapter and we wouldn't be having big fights about it.
