It's not the routes which have numbers. "route 10" doesn't mean anything 
here. It's the junctions which have the numbers. Say I'm at junction 
number 10, and I go to junction 20. That route will display arrows with 
the number 20 until I'm at that junction, but if I would start from 20 
and go to 10, then I see arrows with the number 10 on the same way but 
in the other direction, hence why the route at this time gets this 
tag "10-20": it runs between junctions 10 and 20.

No, at a junction you get signs like:

(5)
← 20
↑ 10

that means: you have now arrived at junction 5, the junctions you can go 
to from here are junctions 10 and 20, for 20 go left, for 10 continue 
this road.
