Probably better. If we assume a uniform distribution across possible win rates of Sedol vs AlphaGo, then update it with bayes rule, we get 33% chance that Sedol will win the next match. That's not factoring in other information, like Sedol now being familiar with alphaGo's strategies and improving his own strategies against it. So there is a good chance he is now evenly matched with AlphaGo, and likely much better than the single machine version.
