That's the thing man. You're overthinking it. It's supposed to be a crossover for fun. They teased some fan theories then left it vague so that it's up for the player to decide.

For a cheap game they sure went to a lot of trouble to bring back the Accel World cast. If cheapness really was the issue then they could have just asked Matsuoka to do a different voice from his vocal spectrum. Seems intentional they made him keep the Kirito voice.
