This contradicts itself
In one part of this article it is saying "By default, programs under Vista don't run with administrator privileges" in a different part it says "This is a little bit silly: just name the installer something else, and Vista lets it through"
This is a contradiction. If the name is changed Vista does NOT let it through. It runs it with reduced privileges! This feature in Vista is designed to ensure that installers do work, it is not designed to ensure other applications don't work, though it may well have this effect.
