> Is there any legitimate reason to have two nodes at the same position?

Consider a road that has a bridge (that is part of a second road ) 
crossing over it.

The ways for both roads will cross over each other, they might both have 
nodes at exactly the same coordinates, but I think OSM convention is 
that they would only share a common node if they form an intersection 
(you can get from the bridge onto the road below)

In GeoBase land there would be no junction indicating that these two 
roads form an intersection.

Another case might be if two roads ends/start at the same point but 
there is a barrier in between.
