What's so special about 3x3 binning in 5D III video?

I hear that the resolution of the new 5D III was chosen partly so that it could do 3x3 binning to make HD video (i.e., it has 1920x3 pixels horizontally).

Could someone please explain why that's better than, say, the HD video coming out of the 18 MP of the 1D X?

I assumed that since there's neither row- nor column-skipping being done on the sensor in the 1D X's video (is that not true?), that this is all moot. I mean, we never fuss about what exact resolution we use to up-res or down-res when printing, so why is video different?
