This NSAP and Ethernet address are in the MAC layer and therefore are 'addresses' in this context. This IP address is in the transport layer and is therefore a 'name' in this context. By saying which one is in which layer you say absolutely nothing about what 'scheme' they are. NSAP is one 'sheme', ethernet is another. But you know that they are both 'addresses' as compared to the class of things called 'names' that are IP address.
Life is a game.
Someone wins and someone loses. Get used to it.
