Indeed. Plus the fact that we have the King Taijitu, which is naturally two-headed and has both heads able to move on their own.

The worst I would expect from the Nuckelavee would be the situation with two-headed snakes in the real world - each head has its own brain, and they sometimes try to act independently.
