Not a pilot so I don't know if they'd use that language today, but there have been more than a few lessons written in blood over the years regarding ambiguous/unclear ATC communications. For example the worst air disaster ever occurred in part because a controller gave the instruction (paraphrasing), "cleared to beacon after takeoff." It was intended only as instructions to be followed after takeoff, but the pilot interpreted it as, "you are cleared to takeoff, then follow these instructions." The airport was under heavy fog at the time so he couldn't see the plane that was taxiing and hadn't cleared the runway yet. Two 747s collided and nearly 600 people died.
