They mean stuff like WoWGlider. Those programs are designed to be "played" by a computer only with no human input.

If you are at the controls then you are fine. If you are half botting and half at the controls (using programs to actually DO things like move around, etc) then you are botting and could be banned.

If you are multicasting to 2+ machines or even just using two keyboards but have to actually PRESS buttons to do anything (even if they are very complicated keybinds, UI mods and in game macros) then you are perfectly fine.
