Digital In-Game Reward and Multiple Copies

Hey, I backed one of the rewards where I have multiple copies of the game to redeem. I was wondering if the Digital In-Game Rewards are a one time use? I am assuming they are. So here’s the question:

If i redeem one code for PS4, then claim an Digital In-Game Reward; Will i not be able to use it on my copy on the Switch when it comes out?
