If there's time to do so, yes, but in the case we're discussing it produces a "glitch" in the brain - a sort-of error interrupt, and in some situations, shooting being an example, that can completely put you off what you're trying to do. If the brakes on your car started responding 50mS slower than usual I think you'd get very fed up with driving it, because of all the false "it's not going to stop" signals that your brain would throw up, even if they were countermanded a fraction of a second later.
