If you don't have pedal reflectors (or even if you do), the up-down motion, side-by-side is pretty indicative of a cyclist and allow drivers paying attention to ID you as such. Same thing with the white reflectors which come stock on wheels of new bikes -- allows other road users to more easily ID you as a cyclist.
