Those are sequals so I don't think that counts, as they're still part of whatever mainline Mario series of that console generation is.
Regardless the whole "1 mainline Mario game per console" philosophy seems more like a gentlemen's agreement than a real rule anyways, they're not breaking any rules regardless of what they do with Mario.
