> an "expert"

Here's the problem: "Experts" (or "veterans" as the author calls them) are not created equal: There's the expert that already knows the code because she's worked on it countless times and already has a very detailed mental model of the code and there's the expert who's a very experienced programmer but has never seen the code before.

Even experts of the latter category appreciate good comments when they read code (surely not comments of the "n00b" kind portrayed in the article but comments nonetheless).
