Yes, but differently. When the light stop bouncing it just uses whatever color it has picked up from bouncing around. If it didn't hit anything, it will return whatever is in the background shader. This won't ever happen if you are using an envirosphere or some such.
I've used this technique similar to a Diffuse IBL light for compositing in post ( to help a figure feel more integrated into whatever photo you want to composite with ) but without an actual light emitting environment, the results aren't very pronounced, just less washed out than a default solid color. So I still needed to add supplemental 'not-visible-in-camera' emitters.
