XKEYSCORE is not a watchlisting system, but an NSA system. Watchlisting is not conducted by the NSA -- it's conducted by the Terrorist Screening Center (TSC) and the National Counter-Terrorism Center (NCTC). I have no idea about the events you're talking about. That said, XKEYSCORE isn't a flagging system at all, but more like conducting a google search. So, bad input always equals bad output.
