None of other callers supplies its action list to 'buffer-match-p'.

This already says so:

diff --git a/lisp/subr.el b/lisp/subr.el

   * `major-mode': the buffer matches if the buffer's major mode
     is eq to the cons-cell's cdr.  Prefer using `derived-mode'
     instead when both can work.
+  * `category': the buffer matches a category as a symbol if
+    the caller of `display-buffer' provides `(category . symbol)'
+    in its action argument.
   * `not': the cadr is interpreted as a negation of a condition.
   * `and': the cdr is a list of recursive conditions, that all have
     to be met.
