Because he's a faker. Xiao was one of the fishiest characters in Gunvolt. He shows up right around the same time that Eden lost one of their top dogs and seems to have intimate knowledge on the workings of the organization. He was portrayed with Alice in Wonderland motifs. He keeps his cards close to his chest. In the Jap script, he doesn't seem to like GV all that much in the secret ending (implying he was faking the friendship), and Nori asks him if he was going to give the pendant to Eden or Gunvolt (which doesn't make any sense for it to come up if it weren't considered a possibility). Whatever the original plans, it seems like INTI has settled on him telling the actual truth about himself, as they did not want to pursue his character any further.
