Hmmm, interesting. But this datasheet describes the capabilities of a discrete NIC and not the ME. Chapter 10 details manageability features. These may be used by the ME but could also be used by other controllers, e.g. a less integrated BMC. And the additional MAC address is optional. However, that's actually simple to figure out. One can just enable things and check the DHCP server's logs. Or in the worst case, trace all traffic.
