It was pointed out a decade ago that non-reinfection recurrences of Plasmodium vivax malaria caused by parasites that are closely related to those from an earlier time point are highly suggestive of a merozoite origin [1,2].
This would make them recrudescences (in an unknown proportion of cases), not relapses. In other words, hypnozoites  have nothing to do with such a recurrence.
Some recurrences that take place after 28 days post infection are also recrudescences (not relapses), as has recently been explained .
