I'm thinking that 1st Mugo was the one who gave the order and 2nd Mugo has fallen for the uke and doesn't want anything to do with the group no more. Which is why they were confused when they saw 2nd Mugo because they thought 1st Mugo gave the order but 2nd Mugo won't allow it no more. 2nd Mugo would be charge and 1st Mugo would just have to deal with it since 3 rd Mugo doesn't mind about it.
