Bug with /remake, I thought first blood before 3 min prevents it?

Our taliyah killed their teemo at 1:31. Their shaco was AFK. They made remake anyway. Why is this possible? Here is the game, am I missing sth or this is a bug? http://matchhistory.eune.leagueoflegends.com/en/#match-details/EUN1/1517805407/213959025?tab=overview
