Falcon 9 doesn't use an FTS manually triggered by an RSO. It uses an AFTS, which is controlled by the rocket itself.
My guess is it was armed for the early stages of the flight (when there was still a risk something could go seriously wrong and the rocket could start heading towards Orlandit), but it was disarmed (or just given very generous parameters) once the rocket was downrange a ways.
