It's for the high burst capability, as well as for heat issues. The MOSFETs used in the controllers are rated for a LOT of amps, but that's at 25 degrees C. At their rated number of amps, they are going to get hot, which is why heatsinks are used, but they will still heat up, making them less capable of handling as many amps as they are rated for.
