I think the comment may be referring to some of the command-line
utilities from Texinfo, e.g. for PDF exports.  There are no new
texinfo references in "octave" after this patch:

However, native-inputs should not be referenced at all, so the patch
LGTM apart from the comment update.  Or maybe it's simply outdated?

Side note: Why is it referring to a different texinfo than the one from
`guix build texinfo`.
