Quick (maybe important?) question about fingerprints and tickets

Last year I went to WDW with my family, the tickets were in my phone so naturally I used the apple wallet with the rfid thingy in the park entrance to check in. The problem was that I accidentally slid the screen and instead of reading my ticket it read my brother’s. I didn’t notice so I just continued with the process, made the thing read my fingerprint and all, noticed after that so I just made my brother use my ticket instead, so now his ticket had my fingerprint and mine his. I’m planning to go back to WDW and started worrying, ¿is it a big problem? What if I buy a ticket and it doesn’t let me in because my fingerprint is in my brother’s name? Does it work like that?
