As to detection of duplicates further back, you're correct that *if* you discard that state, you won't be able to detect duplicate packets.  An implementation that receives a packet older than it can identify then has a choice:  Either it discards the packet, or processes it.  Processing a duplicate packet is merely sub-optimal, not fatal, since each frame inside should also be recognized as superfluous.
