Logically you are correct, however there may have been other purposes in mind when the lenses were designed that never saw the light of day. Among older Telyts, the 400mm f/5 and 280mm f/4.8 will cover 6x6. I've also seen a 400mm f/6.8 adapted to 645 (I think) but I don't know how the performance is at the edges. More often I'll see the 280mm f/4.8 adapted to 645, 6x6 or even 6x7.
