It does, and it's almost completely correct. There are two planes. One 
has the original image, and it remains unharmed. The second plane is 
above the first one. It contains the blurred highlights using parts from 
the original image. All darker portions are transparent. The upper and 
lower values are controlled in a pigment_map, and allow for a smooth 
transition from transparent color to image-based color. (if that made 
any sense :)
