No, she said she was a specialist. She said that Caity was thinking about pursuing the same profession and even going into the same specialty.

I agree that Caity is far enough behind her that it won't make a difference. Also, in several years of medical school, Caity may change her mind about the specialty. She may find something she likes better. If she hasn't yet gotten into med school (which "thinking about pursuing the same profession" implies she hasn't), she might go to a med school in a different city and end up practicing someplace different. So many things could happen.
