Cheating isn't defined in online chess as that, it's defined as using outside help. That's just a description of the (flawed) detection mechanism. I think it's an incomplete description to, I'm pretty sure move times are also taken into account, and lichess apparently uses some client side behavioral signals too (and doesn't let you play via API in the fast time formats where those signals help). It's still cheating even if you aren't caught.
