It seems to me, it is advantageous for the animals to fight for the territory up to a certain degree, where plus-munis delta territory does not justify more fighting, so they sort of agree on some point, be it a clear small fence in this case, or, what I would imagine happens in nature, a somewhat broad imaginary line. So both of your points stand.
