I remember an explanation by some Google employee a while back for the Google Home that was basically this, but a layer further removed. Basically the activation causes audio to start getting streamed to the cloud backend. That runs some more thorough checks on the activation ( like checking for massively concurrent activation with the same audio, etc...) and tells the device to stop and disregard the current activation.
