Meaning that Ako and Tsubaki were brothers because they are from the same father. But they are also cousins because they are born from different mothers. The same could be said to Tsubaki and En.
Cousin = Pinsan, I'm sure you understand what that means.
And since they are from different mothers, but the same father. Then it means that there are three girls, and one boy in the previous family.
Okay, now I understand. Thanks~
