the nether is always equal to the seed your using...well at least for us PS4 folk...I don't know about Xbox or PC.
I know because I made mistakes in the nether, things I regret, but after a quick reset everything was back in place in the same spot.
Even after using my ps3 seed for my ps4 before we had the transfer option the nether was still the same even taking into account that the ps4 world generation is not the same as the ps3 and it will do some slight changes to your world.
