Now if I understand correctly paths (but not textures) were removed from all railway Y interchanges in the latest NAM update so trains can't go from the right fork to the left fork, right? Well it seems for one type the pathing still exists.

I don't know if it's a game limitation but when a straight track is added through the centre of the wye the very unrealistic U-Turn pathing becomes active. I have not yet tested the Elevated Rail but I imagine it is experiencing the same.
