That could be true, but according to some articles I was reading at the time (sorry no src), the nature of their engine is that you cannot determine just how strong it is by playing one game because it plays to "just win", and not to win by as much as possible (paraphrase). So maybe it was barely good enough to be 2p, maybe it was already much stronger.
6 months ago it was clearly stronger than Fan Hui 2p. You don't beat someone at that level 5-0 without being consistently stronger.
Fan Hui said the machine played extremely consistently 6 months ago. He said playing the computer was "like pushing against a wall" - just very strong, very consistent performance.
