I remember Don Kiskey had a segment on one of his tv shows about 6 years or so ago where he showed footage of when he found a target buck he named "The Switchgrass Buck" had died of the exact same way. It appeared he was rubbing a tree on the the lowest side as the double trunked tree was on a slight hill. He apparently lost his footing and wedged his rack deeper into the crotch of these two trunks and could not get free. The yotes cleaned him from jaw to tail. What. Brutal way to die!
