I think that this is an oversimplification. That's somewhat like saying that the way you use a sledge hammer is no different than how you use a claw hammer, because they're both hammers. Anyone who tries to hang a picture with a sledge hammer will be rather unhappy with your advice. Though at some level how the data is stored is indeed an implementation detail, to take full advantage of the fact that it is requires re-thinking schema design and in some cases even query design.
