My stats

[BH2O]

I still think variance will kill him even at low limits, but I see your point SG. Most of the low stake tables play very passive. So if he is betting his big hands, and checking down with mediocre holds I could see him being profitable. Once he moves up people tend to make him pay more to see later streets with the mediocre holdings. If you look his stats the VP$IP goes down as he has moved up, but his aggression factor on later streets stays high. He could very well understands the game, but isn’t adjusting to his competition enough.
