Yes, you are wrong.  emacs-xtra.txi is part of the single Emacs manual
(which is why you don't see info/emacs-xtra.info after you build
Emacs).  The reason for its existence is explained in the following
comment at the beginning of emacs-xtra.texi:

  @c This is a separate manual to avoid making the Emacs User manual too
  @c large in print.  In the Info format, the chapters included below
  @c are part of the Emacs User manual.

Today's lesson: it is not always enough to find some Grep hit, you
should also look around to make sure that hit indeed supports your
theory 😉.
