The other way around--you will coast farther, so to get back to coasting the same distance you have to start coasting at a lower speed.

You coast further because there is less friction with the transmission out of gear. No compression braking, just tire-to-road, wheel bearing, and transmission internal friction. Which is a lot smaller than the friction from compression braking.

Make sense?

Oh, and on an old carbureted car, I would not want to turn the engine off while coasting. I'd be concerned that it might not re-start gracefully, and it might use quite a lot of fuel when it does.
