What happens if someone claims the territory right next to mine?

I'm having kind of a hard time with this, if only because our wolves are so humanized. Fox has done several non-realistic wolf things, and most characters on this board have. A lot of what was said in the above post is based on a character's personality. I know that Fox won't stop being territorial just because a new rule is put in place. That would be changing her personality.

a wolf from OS can't march into a pack territory in NWF, for example, and tell them to get lost because the inner claim, or true claim, is in a whole other area (and technically is miles away).

I guess this is a good example. I feel like the above scenario should definitely be allowed happen. It doesn't mean it would have any merit or that the OS wolf wouldn't be eaten for trespassing, but he/she could still do that if they wanted. Just want to make sure that part of it isn't changing.
