When you are on a Genocide run, you must be LV 19 to fight Sans and continue the route. You can still mess up your run in Hotland/CORE, so if you don't kill everyone there, you still fight NEO but he reminds you that you screwed up. That's why you get to LV 16 if you don't kill everyone, it changes back to the Neutral run because you aborted the Genocide.
