I mean, this specific scene in any iteration has never really added to the story. Whether Pan Segment, Pirates Segment, or Pocahontas Segment. It was always just another part of Mickey's dream, and was always meant to be fun, live action sequence.
I'd say Mickey asking for help very specifically in this version does tie it in further, as he needs a hero to assist him. Perhaps they could have tied it in further if each segment helped Mickey more clearly in some way.
But I'd still argue this is an improvement over the Pocahontas scene, although I'd like there to be more performers in the Mulan sequence, and Aladdin sequence.
