Lagswitchers do exists but the one you mention is not one. It is simply put game having poor netcode, so all the actions you perform immediately start their animation even before they are authorized to go off. Once authorization fails, you see an animation of an action that is not happening. You get it more with laggy games.
They intentionally omitted an industry standard called lockstep that prevents this issue, to hide the fact how rubbish their netcode connection speed is.
