It doesn't. The purpose of showing that link was to show how difficult it is to now bhop in zm and should be relatively easy to catch a scripter. Basically if you see a zombie consistently bhopping (gaining speed) like in the ol'days, he is most likely scripting since achieving such a feat is inhuman.
Another way to easily identify a scripter is to monitor his actions. Most, if not all scripts, give off a robotic impression.
Ex, camera not moving up or down, only moving left and right. Camera moving left and right at the exact same points.
