That exactly is. There's no difference between using disc2app to rip and install your own disc and download the game via uTikDownloadhelper, wich downloads the disc ticket from that ticket site. That was, in fact why there was such desperation for the Breath of the Wild ticket to leak, because people were waiting for someone to get the disc and leak the ticket, and that's also the reason why the original BotW leak couldn't be played w/o sigpatch, because even being downloaded via NUS it didn't have a valid ticket.
