Unlikely that they mistook the CRJ, It's landing lights were pointing right at them. More likely they weren't sure where they were in relation to the plane and where it was going. From the radar plot they are head on, then the CRJ turns final to 33 and the Blackhawk turns right to avoid them. Too high and in the wrong spot.
