Good question. Looking at it technically, I agree that
the above two cases exist. It might be another question
whether the MOBIKE protocol needs to "optimize" for
both cases, or whether support of the second case is
sufficient. (There are mobility protocols that make a
very optimized design to ensure that no packets are
lost even if the packets have already been sent,
but the necessary mechanisms are also extremely
complicated.)
