As far as I know he never gave a detailed description of how he cheats when playing online, he only admitted that he did it, and only admitted two instances, though from the recent chess.com response it sounds like it was more consistently than he admits. My best guess would be that he has a friend shadow playing the game on AI and uses that info to figure out when Poot une moments arise.
