I've never assumed that the sticker would give you a special line at security. I transited HKG on SQ 1 from SFO to SIN and also was given a sticker to wear. I think they do it so that it makes it easier for the airline staff to find you if you happen to be wandering around the terminal as the boarding gate is about to close.
