I'm pretty sure this happened to my wife. I read earlier where someone said their name matched someone and flagged them to secondary. Well - I went through with my wife (her first time using her nexus) and she was flagged - it was not RR, so I thought she may be okay originally. We went in and we had a very helpful agent. She explained that the computers will do matches on many different attributes. If it finds a match to something, it will flag it and it's off to secondary. She said, in my wife's case it was her birthdate. Believe it or not, that matched someone they are looking for. (All she said.) She said every time she uses Nexus she will get this and to not use the machine next time and go to the crew line and explain the situation. It will be faster and save her the time. Helpful.

It appears their list to check against does not cross match with the Nexus data very well. I'm curious how they eliminate people from being suspects.
