Sasuke only ever had yin release. But regardless, it's pointless to talk about yin or yang release in this battle. Nobody really knows for sure how yin and yang work in Naruto except for genjutsu, and it's not like in this battle the 2 would try to genjutsu each other, because that would be dumb. They are both master genjutsu users, and it would be pointless to try genjutsu.
