It minimizes shifts in color saturation, adjusting only the luminosity which affects the contrast more precisely. For grayscale images, or adjustment layers stacked above a Channel Mixer adjustment layer, Normal and Luminosity modes do the same thing.
I made sure to specify it for Dave because he said he was getting oddball colors. This minimizes distracting color shifts when working on full RGB color images.
