It could be async verification - my subscriber client always uses sync, but other clients probably default to async. Using async means that there could be a delay before the subscription is verified, and it might be the case that adding a sync subscription to the mix forces the pending async requests through. (Honestly, though, this is mostly wild speculation.)
