 Yes, exactly.

 So how can I fix this "bug"? It seems that session key is decided by
 negotiation.
 Can we de-couple Negotiation from connection?
 Then we have: connection (1) ---- (1,*) negotiation (1) -----(1)user

 Or multiple users share same session key is not unsafe. In this case, job
 will be simple.

 Thanks
