Surely though it is better to specify that the segments *do* have to be in 
a specific order, to avoid undue complexity in making sense of them? 
That's arguably another argument for superways: branched streets can be 
dealt with using one way for each branch, then a superway to group the 
whole lot together as a street entity.

A simpler solution still would be to remove segments altogether and have 
nodes, ways and super-ways.
