I think that, simply put, this means the Harmony "knows" when something is on or off and which "inputs" are active etc.
You can press the "watch" movie activity and everything will come on correctly, then press "listen to music" and the DVD player will get turned off, the CD player turned on, the TV turned off, and the surround settings changed from "cinema" to "jazz" (for example). If you then press OFF, the Harmony turns everything that's ON off, and knows not to "toggle" any of the other devices (which would make them come on or turn off by mistake). I am sure there is a better explanation but I noted that you seemed to be getting impatient!
