They could see it, and they turned to pass behind it.
Unlikely. The helicopter crew was told about the CRJ approaching 33. At the moment of that initial traffic advisory it meant, the CRJ would first cross their flight path from right to left, and then later on final (circle to land) from left to right. Did they simply expect still the former, seeing the second jet approaching 01, misjudging the timing / distance as to the CRJ, and therefore turning right to pass behind / give way to an approaching aircraft espected to turn any moment and cross their path from right to left?
