It is not about an external network interface, but external traffic/devices. The NAT in this case is a port forwarding firewall, like Amazon or Google cloud, where you have a local address on server and the firewall is forwarding by port all traffic from an assigned public address.
Such scenario is quite common in enterprise environment, the devices on local network connect by private IP, and the external devices connect to the firewall ip and this one does port forwarding.
