Your car lights are pointing ahead of you -- but there's a bicycle coming on a cross road towards you. (Let's go ahead and say you have a stop sign at the intersection and he does not.)
Or there's a bicycle to the right of you, matching your speed.
Or you're about to make a 90+ degree turn, and there's a bicycle over there on the cross road. (Your headlights might catch this one, but probably not well.)
It [your headlights are not pointing at a bicycle that you still need to see] is not an unlikely scenario at all, and it's one of several reasons why reflectors are not sufficient.
