The requirements for multigrade and colour paper aren't quite the same, the numerical values for magenta might be higher than the value that would be measured if the filter is evaluated as a green bandstop. Whether and at what exposure compensation colour heads can reach the full range of multigrade papers always is somewhat debatable.
But it is not really a practical issue - if you need a gradation of 5 over 4.7 (or 1 over 1.3), your negative has issues that are rather beyond the scope of silver printing, and you'd better rescue it in a digital post. Most currently available fixed-grade papers aren't even made in these extreme grades.
