Not really surprising. She apparently came across well in that role and the role was noted in her credits. Thus, when a producer/casting director needed a bit player to fill a similar role, they ran a quick search and her name popped up. Then someone said, "Hey! She came across well in XXXX" so they contacted her agent. (Supposition on my part.)
