Its the amount of O2 mix which sets yout MOD, not the bottom depth
Its quite possible that your mix is too rich to assist your buddy although its unlikely that you would be daft enough to choose so different a mix. I get the impression that BSAC are just trying to cover themselves here as Nitrox is a pretty broad term and covers any gas between (22% O2 and 99% O2).
