As far as I understand, for subproject commit "bind" link (and perhaps the
keyword/name "link" or "ref" would be better than "related") point to other
subprojects commits (trees), while the Sam's "prior (3)" example link would
point to the toplevel project (gathering all subprojects) commit, and it
would probably be named/noted "toplevel", not "prior".

Am I correct?
