i misread that "using" as if it had a "by" in front.  in the rendered
texinfo (at least for me), that paragraph reads as:

      Go forward to a place from where you previously went back using
   ‘M-,’.  This is useful if you find that you went back too far.

and there's no reference anywhere to xref-go-forward, so it's hard to
infer that that sentence is referring to that command.
