Because this is precisely the opposite of what I've observed. It seems to me that the ASPH (we are talking about 35mm Summicron-Ms, right?) achieves greater... we'll use the word "sharpness" for lack of whatever the truly precise word would be... at the actual plane of focus, but that it blows out of focus at a higher rate as that plane is left.
