I think that when you exert some pressure on blood vessels, the blood has to have higher pressure to pass through. While arteries work at higher pressure, veins have a lower pressure. So in the arteries deliver blood regardless, while veins accumulate more than usual until they are pressurized enough to let excess blood through the cuffs, accumulating blood in the legs. All of this is purely my speculation, though.
