Pretty close; i'll explain the difference since you're a novice: Yates has extreme separation and definition in the medial and lateral heads, which is why he looks good on the side tri pose. Howerver, given the overall lack of size, no one's been able to come up with a single Yates tri shot that looks good outside of side tri. You're welcome for the education. 
i specificially mentioned the side tri shot.
also note the forearms and even biceps in that shot.
strange how not many people can compare with dorian in that shot - arms included, but in other shots, his arms are very average.
