Fast forward to the part where Robin and Azeem are going to catapult over the wall of the castle. Take a good look at Azeem's sword as he gets on the catapult. He has it in hand, facing outwardly right? Now when the camera changes angles he turns it around and it is facing inward next to his sheath. When they are launched over the wall the sword is not in hand anymore as it was a moment later. Finally when they land in the pile of hay Azeem retrieves his sword from in his sheath. His sword changes places a few times in a short time span.
