Do you mean that a commune (the lowest level of self government) can 
be part of more than one unit of each of higher levels? Like this?

I am talking here about administrative boundaries not some sort of 
customary ones.

I haven't written that earlier but what should I do if the boundary 
goes along some other way like railroad, river or highway? Should I 
draw another way right besides the road or tag one way as both the 
road and the boundary?

If the former then I think sooner or later we should develop 
separate layers for different features of the map. Editing could be 
much easier then.
