If so, it is still debatable because he reported the bug and experimented which things could be done with it to report it.
But if by doing so, he won a lot of matches and used the bug to his advantage every time, it is a perfect reason for a ban.
I think the key factor is how often did he use it, because to learn how a bug works to report it you must use it more than once and after you learn how it works, if you still use it to win everytime it is clearly your own fault if you get banned
