I'm not 100% sure with that particular broadhead, however to be safe, if i were you, i would do my best to not hit the the equivalent of the human humerus (upper arm bone), or scapula (shoulder blade).
And if the deer is 5-10 yds away with an Xbow, waiting for a broadside shot hitting behind the shoulder or quartering away shot seems doable to me, especially if not spooked.
Be sure to watch the wind.
