There is a deadline for the entry of each event.
It would be too late if they wait and see the results of all four events.
So, it is quite normal for JSU to keep the entry to anyone(usually the one assigned the first event), while at the same time, register all other players as substitutes.
They can replace the entry considering the results of all players.
The name "Kondo" is a kind of "dummy". It's not decided yet who will get the second assignment.
