First off, Dual Blades refers to a skill in the game's system that allows using Sword Skills with two swords simultaneously. Dual Blades is not available in ALfheim Online and Sword Skills weren't yet implemented at that time either. He used two swords, but not Dual Blades.

Kirito's trick with two swords worked, because Gram apparently couldn't handle consecutive blows that well. With Yuuki's ultra speed, I doubt that Eugene would have much use of his sword's special ability.
