Reflect can be on any light, too. It's a relation between reflective surface, reflected object and camera. Iow, you can have reflect on a global with no shadow pointing into space and get the same result. This frees up your primary shadow casting light to get the job done right(Shadowmap or RayTrace). "Add reflection" command also auto- connects to an existing backgound pic if in place. Connecting an image map to a light can preoduce nice effects... Generally the more "bounces" the better (resource intensive though).
