My therapist self discloses in a very general and vague manner. For example, she will say something like this: "There have been times in my life when I've felt that way, too." She does not disclose anything about her family, hobbies / interests, vacations, etc. but she will --- and only very rarely --- self disclose about a personal experience that pertains strictly to herself. I appreciate how she self discloses and I would not want it any other way. It just works well for me.

Just my two cents here but I think it's okay --- in fact, it's more than okay --- for you to carry on with the topic at hand without further discussing your therapist's self disclosure. It wouldn't be good etiquette among family and friends in real world conversations, of course, but therapy is not the real world. Keeping the focus on yourself in therapy is the very best thing you can do for yourself and the world for that matter.
