Could you provide an example permalink? I do not get this behavior from the script.
It's been recommended since I started editing that no two segments should have the same two end points. The guidance has been to split one of them so there are always at least three segments involved in any "loop." If you don't do this several minor problems can occur. First if you start or end a route on a segment that shares its endpoints with another segment, the route line may display on the other segment. Second, routes over such a segment may show using the other segment in URs. Third, if you deviate onto the other segment, it seems that waze does not recalculate the route (admittedly not a significant problem as you end up at the same point anyway).
I believe that somewhere it was explained that these issues are caused by the routing engine identifying routes by junction nodes rather than segments. Thus if you have two segments that connect the same two junction nodes, when the various display engines get the instructions from the routing engine the route is ambiguous. However, I can't remember or find who posted this explanation.
