What did the other tire do???????? Is the other one on the ground, or did it turn???? Open rear, the other tire turns the opposite direction. Posi rear, other tire turns the same direction. Need to know that. I would think you have an open rear end. I think you need to hold the one tire while turning the other. Then do your count. You need to be fairly accurate on the drive shaft count. Not much difference in a 3.08 and a 3.36. Or a 3.55. Mark the drive shaft so you can be sure of the exact number of turns, plus a partial turn.
