Ah yeah, I phrased that badly. My intent was to emphasize that the cheat exists solely outside of the game executable. Blizzard runs an incredibly cool, and secretive, program called Warden to do exactly what you said (amongst other things). Details are sparse but my understanding is that every 30 seconds a unique copy is downloaded and run looking for cheats. For small time developers, cough cough, it's a painful problem.
