I don't see any error in the text you quoted.

This message means that the `(bootstrap-)emacs` executable used to
byte-compile "that" file was built at a time when loaddefs.el was
different, so before performing the compilation we reload loaddefs.el to
overwrite the preloaded settings with its new contents.

IOW the "stale loaddefs.el" is the one that was preloaded rather than
the current file.

I guess it wasn't a great choice of word, indeed, since it makes it
sound like the current loaddefs.el is stale.
