   That is my first thought, too, though....   
      
   Ping the first host, the ARP entry is added on the PC and the   
   switch adds it to the forwarding table.   
      
   Ping the second host, ARP adds it, switch changes the table   
   when the reply comes back.  ARP doesn't remove the first entry.   
   (It could be more than one IP address on the same host.)   
      
   Ping the first host, the ARP entry is still there, switch forward   
   to the second host.   
      
   Unless the first host sends out anything, or the switch entry   
   times out, yes, it seems that is what would happen.
