Even ignoring that everyone comes to a stop at a redlight and you lose the progress, you genuinely only save three seconds of time, like you said.
Devil’s advocate: sometimes those three seconds mean they make it through the light and you don’t. And that lead stacks with more and more intersections along the trip.

No, he didn’t say you save any time, because you don’t.
He specifically was taking about 3-second follow distance.

Presumably the person saved a whopping three whole seconds.
