The way I could see it working, is if you have nearby pixels that are wholly one color across a quad. Then you get essentially a fixed value for the bottom two layers you can subtract from the average from the other top layer pixels of the quad, and get better guesses for the remaining top layer pixels in the quad.

If you are illuminating the top quad with light that varies with brightness but does not vary with hue, because data from all three layers are used to calculate hue you will get unwanted hue variations across the top quad.

I think it is likely that the top layer is binned for all hue and chroma calculations. Then the data are used from each individual top layer photosite to calculate luminance for that pixel.

That seems to be the most likely method.
