Indeed it is, but this was the long way to demonstrate how it is derived. And is besides the point, as we were talking about tunnels and they don't have a MAC address of their own, so you can go ahead and directly configure an EIU-64 or modified-EUI-64 IPv6 address directly as show in the short way.
I just want to point out that this discussion is *not* about tunnels only. It's about generic addressing plans for point-to-point links, and the failure of /64s to address the needs of *ops* types. Yes, of course you can put whatever you want into an EUI-64 identifier for a single /64. Unfortunately, ISP networks usually consist of *many* point-to-point links, and all of them want to be addressed in a structured and time-saving (!) way. Which means "use some of the available bits to do structure" - and if you use up a /64 per link, you need those bits further up, and those are just not there in the current policy frame work. (If the RIR->LIR allocation/assignment framework is changed to hand a /16 to every LIR, such a scheme might not be a problem. In the current scheme, it is).
