Hey I saw that live ! He did not stream snipe. There was a tie breaker and 2 people from his team grouped up with two people of Lupo's team for one game. His teammate told him when to queue up to have a chance to be in the same game and help his team mates. It's of course shady as hell, but it's mostly funny. It should also be noted that Lupo was in the tie breaker in the first place, because he had viewers queue up at the same time as him to help him and that netted him a crown in one of the games.
In any case, the rules for these Fall Guys events are almost always dumb and unfair, because the game is not designed for competitive play. I am not sure why you would punish people for getting creative as long as they did not break an explicit rule. Just adjust the rule set for the next time.
