Honestly, if it can play top tier StarCraft matches, I'm willing to be we could apply it to the vast majority of things humans can currently do; although I'll rule out creative tasks for the time being.
So many aspects of SC:BW are currently balanced around extremely micro intensive unit matchups (mutalisk versus marine and medic, mutalisk versus templar/archon, lurker versus marine, science vessel emp versus arbiter) and so many units and abilities are actually borderline unusable at a competitive level because players don't have enough time to spare (the dark archon's feedback abilitiy is on paper probably one of the most powerful spells in the game but virtually never gets used because the micro opportunity cost is too high, medics optical flare is another good example, on paper it is an extremely useful ability but has only been used to good effect once or twice in pro games) that once you get a half decent AI playing the game won't resemble anything played by humans.
Hell, even worker rushes might be unstoppable in the hands of an fairly rudimentary SC AI. Timing attacks like the bamboo, JoyO, and bulldog coupled with a perfect worker rush backup would so radically alter the pool of viable strategies that we would essentially be starting from square one in terms of build orders.
They'd benefit best by categorizing attack strategies, counter strategies, aspects/units on map, and so on. The DeepMind system would do all that in a way that converts raw data into small, actionable information. Traditional methods could do pathfinding, buildup, time-limited decisions, micro-ing, and so on. A hybrid system seems best here.
They're not just going to throw DeepMind at it and beat good humans. We'll find its patterns, then outsmart it. Especially the pro's.

EDIT to add:
I suggest a title change along the lines of "DeepMind will try to beat StarCraft next." That's more accurate in terms of both reality and original article.
And then it will learn our patterns and use them against us. AlphaGo for example, uses the patterns of millions of matches and builds on them.
Interesting how deepmind started with atari, moved to go, and is staying on mastering games.
