Actually, it's about 20% more, not 30. And, no, two 5850's aren't "pretty much" the same price as a single 480. In fact, the price difference between the 480 and 5850's in SLI is as much or more than the difference between a 480 and a 5870.
So why is it ok to compare a 480 to $100 more expensive setup but not ok to do the same with the 5870?
People compare the 480 to the 5870 because it's the fastest single gpu card from both companies.
