>This strikes me as very weird, since there is a Tocharian language group and Iranic languages don't belong to it.

I guess it's because "Tocharian" as used for IE languages of city-states of Tarim considered to be a mistaken name now. Eteo-Tocharian means True/Real Tocharian, and doesn't mean it belongs to "Tocharian".
