It's also because most of us poop in a sitting position. Squatting, as you would do outdoors if you didn't have a toilet, spreads the buttocks and there is much less cleaning needed. It also promotes more complete emptying so you don't have fecal matter left "pinched" in the anus that needs to be wiped up. If you use a typical western toilet, get something like a Squatty Potty to prop up your feet and you'll find you need to do much less wiping.
