Disclaimer: Some of this is speculation.
The actual PSN/Epic Store DLC codes are basically products, and they can't realistically make thousands of unique products for single users on the storefront. As far as I know, all of the DLC products need to be set up by hand and I'm not even sure if the storefront even could support thousands of possible DLC products for a single title. The DLC basically serves the purpose of identifying that you are a backer and all backers get a code for the same product add-on.
The in-game backer code identifies who you are, because some of the rewards had specific "find your X in the game and get Y" rewards. As to why they couldn't just do it in game only since the backer code option is visible to everyone, perhaps this was their way of keeping backer-exclusive items away from non-backers. There's nothing to prevent a backer from sharing their unique code.
Since nobody has backer codes yet, I don't think we know yet specifically what happens if you haven't downloaded the DLC and try to use a backer code. But my main answer here is they probably did it this way to make sure only backers can get the backer rewards. (Although the PC version will probably be hacked for everything at some point)
Ah thank you, that makes so much sense that I think you're bang on with your speculation. Cheers.
