With the CRJ crew probably having their attention focused to aim for runway 33, while performing the circle to approach. With a "clear to land" obtained, they even might be less aware, there might be something out there on a collision course with them.
Not to say, the helicopter declared a "CRJ in sight", which also implies from that moment on, the separation became their responsibility.
When flying myself, I am very hesitating to "accommodate" to ATC's information about other aircraft around me, since I then take over the separation responsibility, even when losing sight of the other aircraft(s).
