No advantage. Assembly constraints are actually preferred. The purpose of this video is mainly just to show a tip/trick and how something like this could be done. Some people prefer to just have one part the part that drives their assembly because they are not aware of some of the other capabilities that NX provides, such as “make work part” to design in context of an assembly.
