Yep, this is the key. All lots should remain open together until there is no more bidding on any of the lots. And the aggregate of the individual bid amounts must act as a proxy bid that the high bidder from the set lot can bid against at all times. Without these two rules in place, the dualing auctions format fails to achieve its goal.
