CFA exam deferral policy

Does anyone have any clarity about the purchased deferral that’ll be available for August 2022 exams? The website does not state the conditions for purchases deferrals, it only talks about that purchased deferral will be available for August 2022 exams

My understanding is anyone can purchase a deferral for any reason for $400. Only conditions are that the date you defer to has to be within the next 12 months and you will not be able to defer that date again. You either have to sit or withdraw from the exam date you choose.
