Well spotted. If using methods 2 or 3 from Franc's original email, presumably we'd also need to add a sequence number (actually two since, as you point out, each way would refer to segments of two boundaries) for each way, since a unique boundary ID is no longer unique to the way, once you've split it up into two or more segments.
