Just because it's possible to do those things doesn't mean he could do them well. Anyone in ALO was capable of using two swords, if it provided such an advantage then why didn't every one-handed sword user make use of a second sword? There is nothing saying that Kirito is more skilled with two swords than he is with one, claiming that he is better with two is pure speculation. I'd also like a source on him saying that he prefers using two swords, as I don't remember that at all.
