That's what I would think. The problem may be even worse when ways need to 
be split to accommodate turn restrictions, if the intersection is modeled 
as four separate points.

I like bringing everything together to a single intersection point because 
that's what it (topo)logically is - a single intersection controlled by a 
group of signals operating together (or stop signs with drivers co-operating).
