Sasha will be skating on the SOI tour this year and IIRC, she's not doing Nats or Worlds at all this season. It's very possible she's working on her numbers for SOI or for any other shows she has planned for this fall.
Well, I can imagine that with her love of fashion, she'd be in demand for costume designs either for tours like COI or if a skater had the money, for a competitor. As far as choreographing, maybe for COI or again, a way to make money for a competitor.
She may not "need" the money but the exposure of design and choreography might be appealing.
