I figure Susie will fuck everything up on accident, like she was saying to Noelle about her getting the evil ending by accident. Snowgrave/Weird is us getting the evil end on purpose with Noelle. Both need to be done for us to actually be able to get the good/true ending. Like how you need to do a neutral/pacifist route to unlock true pacifist in undertale.

I do like the idea that it's a reverse undertale situation. Where to get the true/pacifist ending you need to do a neutral run at least once. Except in deltarune you need to do the evil route at least once, and then pivot into a normal run.
