Some MSAA+fmt combination require writeout to be split. Right now, it only impacts blend shaders since we only support MSAA 4x, and the only formats that could exceed the 128bit/pixel limit in MSAA 4x are not supported by the fixed-function blend unit. We thus rely on the blend shader to split things properly. Things will change once we add MSAA 8x/16x to the mix, since even the blendable formats will exceed the 128b/pixel limit in that case.
