When binning, the sensor has to add the contents of multiple pixels together and the KAF8300 does this via a horizontal shift register that isn't big enough to hold the maximum possible number of electrons. The result is horizontal blooming as demonstrated here:

Some cameras reduce this effect by turning the gain down when binning. I believe the QSI cameras can do this. It's not a perfect solution but I presume it controls the blooming.
