What's the variable buffer-mode-line? I can't find it in the Emacs Lisp
documentation, is it something you added?

If buffer-mode-line is a buffer-local variable, you need to loop through
all buffers, changing to each one and running your function.
(defun update-mode-line-all-buffers ()
(save-current-buffer
(dolist (b (buffer-list))
(set-buffer b)
(buffer-update-mode-line))))
