(I'm not following this thread, BTW.)

"Matching" typically has a connotation of pattern
matching.  In the case of Emacs it is especially
about textual patterns matching text.

If you're testing a buffer object, and not just
its text or its name, then it's probably better
to speak of the buffer "satisfying" a condition
or a predicate than it is to speak of it
"matching" a condition or a predicate.

In general, patterns are matched; conditions and
predicates are satisfied.
