I read this a lot, but it's wrong. Any reputable text will verify that, when played correctly, variance in Omaha is about 50% that of Hold Em.
You talked about O8 later and I'm not sure if you mean O8 or just Hi here, but Omaha Hi is far higher variance while you're right O8 has far lower variance than HE. Especially against bad players, typically in O8 if an opponent sucks out they'll only suck out for half the pot. It's a pretty good game when worst case scenario you get your money back and best case you take their stack.
