I think I am missing something here. Why does ISATAP have a "model of 
host" and "host variables" if it's meant only for router interfaces?

I suspect I misunderstood the point. Otherwise, yes, indeed, several 
implementations uses ISATAP as a last hop network, connecting several 
hosts to an (upstream) router over a virtual link.
