Burley has aligned the hitch along the centerline of the trailer and not along the centerline of the bike. This allows the trailer to track straight and makes towing a Burley trailer easier. If the trailer was designed to pull directly behind the bike with the centerline of the trailer aligned with the centerline of the bike, the hitch would have to angle to the left side of the trailer to hook to the bike. This would make the trailer want to constantly drift out and the trailer would not track in a straight line.
