Yeah I figured there had to be a code to it. I just didn't expect it to all blow up if I got it wrong. I didn't even see the wall of lights. Like I said, it was a hilarious surprise. But the mission console isn't indestructible, so a new player might accidentally blow it all up and miss some dialogue. I had the same thing happen to me in the GLaD hideout. I was granted access to the self-destruct room before I was supposed to, forgot what the switch did, and blew up the base.
