You're not wrong, but the arp-cache is usually populated when it comes 
time to sending, so sending arp-requests again isn't usually required, 
although it would require that nmap reads the arp-cache of the system 
instead. I'm not sure that's available to userland on windows, but it 
might be. It would still have to send arp-requests for IP's not in the 
cache though.

It must be available to userland in some fashion as arp -a is implemented.
