I think this is perfectly valid topology.

It could be that one end was a router (with high flexibility for VLAN
assignment), and the other end a switch where VLANs are a global
resources, and hence some of them occupied. We have to consider that at
some point these might be automatically generated.

I think this behavior is correct, do the union of the two labels sets for
demarcations (which is equivalent to dropping them, just another
abstraction).
