Even if you were to make the argument that it is an APM bot, you'd still have to explain how those clicks ended up in the right places.
This is a monumentally difficult task. Just ask the players who played against it, they're the ones who should convince you.
Really disappointed at the "well that doesn't count" armchair criticism. Even a moderately skilled player who can perform the basics of the game will out-strategize the basic computer scripting that came with the game. They didn't just win based on click frequency, they won because they understood the strategy of the game. That's huge.
