When a candle is blown out, a buoyant plume of unburned fuel/air mixture continues to rise for several seconds. By bringing a combustion source close to the plume, the mixture can ignite and flames will propagate back down to the candle wick to reignite it. Watch the slow motion replay near the end of the video and you can actually see the flame front propagate downward. (Video credit: G. Casavan, University of Colorado)
