Even taking into account his negotiated edge, which is impressive, it isn't enough mathematically to account for such substantial winnings over such a short period of time. I agree with what others have said and think he must either have had a counting system or had a terrific run of luck.
Great runs are rare of course, but not unheard of. The reason people don't hear about them often is that very few players play at such a sophisticated level to minimize the house advantage to a paper-thin margin, and even fewer do so at a high-stakes table where this would make big news.
