In the UK I know traffic is indicated with a relative position and altitude: “traffic at your 10 o’clock, 2 miles, altitude 1500 feet”.
The ATC for the Reagan crash did not indicate a relative or absolute position, only referencing “the CRJ”, which might be hard to identify in the dark, and the helicopter pilot may have assumed he “had visual”, but was looking at a different aircraft.
