It only works when you're queueing into leveling roulette in a full 4-man premade (means, also no AiN bonus for you). Otherwise it will just assume you have the setting turned off.

They probably enforce this limitation to ensure newer MSQ'ing player will always have steady supply of randos to fill in their queues via roulettes.
