You'd technically be doing a 75% water change over all (50% of the old water the first time, then 25% of the new water and 25% of the old water the second time). Doing two separate changes gets rid of most of the old water, but keeps the water levels relatively high so the fish don't hit panic mode. It's just a method to keep their stress low
