I'm not sure that's correct. I first put my UNI tix in my GPay wallet, then decided to print as backup. For the print, I was asked to check box if I had lost them (which I didn't check). If so a new barcode would be generated. I assume once a barcode is scanned at the gate, it is immediately invalidated for future use. I'll have both for UNI and will try phone first to see if you are correct.Generally your tickets are valid with the last thing you do with them. So if you put them in your wallet and then the next day print them, your wallet ones will be invalid. You would need to then delete from your wallet and put them back in there, which then makes your printed ones invalid. I don't know if ISUs are that way, but remember dealing with online ones that were. I don't remember the rules ISU had last year, I just left them in my wallet.
