According to Dr. Raney himself in a discussion on the MetaCard list some
years ago, this is a feature.  He noted the efficiency it affords, since you
can often do only one evaluation and rule out the need for the others.

FWIW, his documentation doesn't mention it either. :)  Jeanne usually does a
great job of expanding discussion of tokens beyond the old MC docs, but
after 3,000+ pages on everything else it seems this one is merely on par.
