Starcraft is a game that is played with mouse and keyboard (or game controller on console). I think in order to say an AI has beat a human, it should have to use the same interface that a human uses. That's part of the definition of the game.
In Go, anyone can place a stone as well as anyone else, it's deciding where to place a stone that's the game. In Starcraft, not everyone can control the interface to the game equally well. Playing Starcraft without using the same interface as humans is like playing baseball with something other than a baseball bat.
Also, I think it's unfortunate that they're choosing Starcraft 1: Brood War (presumably because of API reasons) instead of Starcraft 2, since there are many more top-level players playing sc2 right now to give it a run for its money, with an evolving meta that could more likely adapt and challenge the AI after it wins some matches. SC2 is where the tournaments and money is right now (compared to BW), hence the best players devoting the most time.
