This is obviously a typo then or at least very ambigious.
Oh, heh heh, that is unclear, isn't it? ;) Well, I can tell you that
there is a historical reason for that, which is that originally the idea
was that the subtype would always be one of a set of pre-defined codes for
certain plugin types (like delay, reverb, lowpass, etc.). Those types are
still defined in AUComponent.h, I think. But anyway, that idea was
soon dropped in favor of sub-type simply being an identifier that could be
any value, as long as it is unique with respect to the chosen manufacturer
and type codes. Seems to me, too, like the docs should word that a little
more clearly...
