I don't know, but it does return a string, which I get in the echo area and in 
the *Messages* buffer.
Try to paste the defun into your *scratch* buffer (make sure that it is in 
lisp-interaction mode),
then evaluate it with C-x C-e and then call it (I don't use supercite, so I 
replaced the two supercite
variables with gnus-cite-prefix-alist):

   (defun my-ask-mail-yank ()
     (interactive)
     (mapconcat
       (lambda (sym)
         (format "%s: %s" sym (symbol-value sym)))
       '(gnus-cite-prefix-alist
         message-yank-cited-prefix message-yank-prefix)
       "\n")) ;;; press C-j here
my-ask-mail-yank

(my-ask-mail-yank) ;;; press C-j here
"gnus-cite-prefix-alist: nil
message-yank-cited-prefix: >
message-yank-prefix: > "
