Not just both cards, but all IP's the system has bound (a single NIC can
have multiple IP's). Some services may just be bound to a single IP on the
system - just scanning one NIC/IP could leave you open if a particular
service is bound only to the other NIC/IP (like terminal services, FTP,
HTTP, etc.)
