The ability for the demons to make clones for themselves when acting outside their vessel accounts for any distance. Given Seth is seemingly not attached to a vessel anymore, his power can't be sealed and he can have his clones head anywhere.

The only major ambiguity is Nemesis' surviving a gunshot wound to the head, which the light novel's indicated would only get healed based on proximity to the vessel (ie, the demon inside it). Granted, there was a clear scar on Nemesis' head in Muzzle, so it definitely didn't fully heal on its own like you'd expect, even when Nemesis had Grim the End loaded in her revolver.

As far as Nemesis' confirmed contract, Allen's narration states and everything he speaks about outside his knowledge in life is based on what Black Box fed to him. He knows Nemesis contracted to the Demon of Wrath but is unaware that the mask the familiar woman wears has a will, so he's seemingly unaware of Seth's true identity. We definitely won't be able to rely on him in regards to Hellish and Seth's actions.

I can support us being ambiguous on this account; until we understand more about Seth's role in that timeframe, it would be a difficult jump to make.
