It's not a typo: auto-save-list-file-prefix is a defcustom from whose
value Emacs creates the name of the directory where it will save the
auto-save files.  The change was supposed to delay computing the value
of auto-save-list-file-prefix until after your init file is read, so
that it catches the new value of user-emacs-directory.
