It doesn't prove that she's right. What it does prove is that aim-lines are invisible to all but the one being aimed at. This was actually already established during the cowboy arcade game where the 1st dude made a weird pose and Kirito didn't see the assist lines.

Given the information we've got so far, I don't think Death Gun is the same LC Head everyone thinks he is. He is either some remnant floating around in cyberspace, or the guy after suffering from severe brain damage by being killed in SAO. He then went overseas and started up this shady company so he could exact "revenge" and continue his killing spree.
