Is anyone familiar with Meng+Scott Allen Burns upsampling?

I'm working on implementing spectral/pigment blending for GIMP's MyPaint brushes (now that we've ported to the version 2 brushes).
I'm trying to learn more about the theory behind the blending, and according to https://discuss.pixls.us/t/mypaint-2-0-alpha-released-with-spectral-pigment-brush-layer-mode/11086, they used a modified "Meng+Scott Allen Burns upsampling" algorithm.

I assume there's some research paper that discusses it, but I haven't had much luck yet finding a specific one by Meng & Burns.
