Afk training is being away from your keyboard while still training. But either way if you are not doing something and your character stops then you would just be sent to the lobby. Unless you are running a script that does the work for you then that is against runescape rules.
Revolution/Auto-retaliation combat is an in-game mechanic -- you will not be punished for using it . As DieHunted stated, if you are forced to click every now and then on the screen to avoid hitting the Lobby due to inactivity, then you will be perfectly fine..
