I don't know why you'd permanently lose the string you matched against,
but m-s-r does let you write

(defun format-matches (fmt regexp str)
  "Replace \\1 \\& etc. in FMT with matches from REGEXP against STR."
  (string-match regexp str)
  (match-substitute-replacement fmt nil nil str))

...in which case you only need to pass the string to one function.
