The lens itself does still move through the distance range at the same speed. So if you track an object or override AF and then let the camera to the refinement you don't gain anything. Only if the camera has to go through the whole range to find the focusing distance the whole process becomes faster because you only have to go from 0.48m-infinity instead of 0.31-infinity. The difference in m does not sound a lot but if you observe how much you have to turn the focusing ring from 0.31 to 0.48 and 0.48 to infinity you will realize that it helps a lot.
