Looks like it.  And looks like it's done on purpose, although I don't know
what this purpose is:

(defun font-lock-compile-keyword (keyword)
  (cond ((nlistp keyword)			; MATCHER
	 (list keyword '(0 font-lock-keyword-face)))
	((eq (car keyword) 'eval)		; (eval . FORM)
	 (font-lock-compile-keyword (eval (cdr keyword))))
	((eq (car-safe (cdr keyword)) 'quote)	; (MATCHER . 'FORM)
	 ;; If FORM is a FACENAME then quote it.  Otherwise ignore the quote.
	 (if (symbolp (nth 2 keyword))
	     (list (car keyword) (list 0 (cdr keyword)))
	   (font-lock-compile-keyword (cons (car keyword) (nth 2 keyword)))))
	((numberp (cdr keyword))		; (MATCHER . MATCH)
	 (list (car keyword) (list (cdr keyword) 'font-lock-keyword-face)))
	((symbolp (cdr keyword))		; (MATCHER . FACENAME)
	 (list (car keyword) (list 0 (cdr keyword))))
	((nlistp (nth 1 keyword))		; (MATCHER . HIGHLIGHT)
	 (list (car keyword) (cdr keyword)))
	(t					; (MATCHER HIGHLIGHT ...)
	 keyword)))
