Wrong.
Datum B allows for up to 0.4mm of datum shift. With MMC from the feature, you can have bonus tolerance opening your TP up to 0.6mm.
The relationship of B and the feature are very important for how the datum shift can be applied. For instance, if B is not perfectly oriented, it could leave you with 0 datum shift, even if it is at MMC.
