To be honest, I haven't used this year's jury tool and don't know how the registration system works. I therefore apologize if I misunderstand the intentions and how it works today. However, ideally (from my experience) the admin should set up all the user names in order to save time for the judges who are not necessarily tech-savvy. For example, on our jury aside from the Wikimiedians, all the judges are either professional photographers or restoration experts/curators. One or two of them rarely use a computer at work, and one judge doesn't have a personal email address. Maybe in other countries you don't have this problem, but for us if we forced the judges to register, they might simply not be able to judge.
Remember that you can also create the account for them on the wiki.
