I don't think the sister will get furious, if the therapist handles the situation tactfully. Having the knowledge that his/her client has si-d doesn't necessarily mean that the therapist has to launch a direct confrontation. If her therapist is skilled, s/he will know how to manuever and work with her without letting her know that she's been "reported," ya know? I think it depends a lot on the tactfulness of the therapist.

HOWEVER before doing that, I think you should try talking to your sister. Ask her if she's told her therapist about the si. Because si is a VERY personal thing, and if I was aware that someone else told my therapist about it rather than me being able to, I would feel devastated and violated.
