I don't understand your criticism. DeepMind's APM is limited, and you're saying there's still a problem because DeepMind will use its APM more effectively? Well...yeah, that's a big part of what it means to play Starcraft 2 better than your opponent, whether it's a human or a computer.
This is how APM is treated in the professional scene as well. Everyone knows that bursts of 500 APM when you're spamming at the beginning of the game aren't some incredible display of skill. But sustaining a good number of useful actions per minute is incredibly important, and a huge part of the mental process in Starcraft 2 is constantly deciding where and how to invest your actions.
