Subject: [Ips] negotiation more than once

I am wondering if anyone knows the rational behind why the initiator must not negotiate a parameter more than once.

   Neither the initiator nor the target should attempt to declare or
   negotiate a parameter more than once during any negotiation sequence
   without an intervening operational parameter negotiation reset,
   except for responses to specific keys that explicitly allow repeated
   key declarations (e.g., TargetAddress).  If detected by the target,
   this MUST result in a Reject PDU with a reason of "protocol error".
   The initiator MUST reset the negotiation as outlined above.
