I'll confirm. You HAVE to be on the same brand to play together. All the teams are rivals, so if you play on the team you're on, you ONLY play on a team with people from your brand. You can travel to other courts when you reach a higher level, but then you can only play against them. So if you want to team up or be on a squad, you need to be on the same team: Flyers, Rivet City, etc.
