Continuity can be had by the lines sharing a node. In the same way roads
share a node to enable routing.

I would expect a line that has n*3 cables to be tagged cables=3;3 (for
n=2, add more ;3 for more n). This would signify that the 3 phase
circuits are separate.
Humm problem in identifying which of the 3 phases is connected to which
when the line splits off.
Who uses this route relation - as in a end use? Or is this a 'build it
and they will come' thing?
