No, he said that the generated code is saved automatically in a file and
if the user puts (some-hypothetical-other-command) in his .emacs
manually, it will load the saved file.  Something like:

(defun some-hypothetical-other-command ()
  (or (let ((f "~/.emacs.d/cache/some-hypothetical-other-command.el"))
        (when (file-exists-p f)
          (load f)))
      (generate-and-save-that-slow-code)))
