Seems to me that as the pionty end is partially enclosed by the wider end, hitting the ground that way will minimise the dirt and abrasives that might pack in around the joint and cause pre-mature wear.
As the track is lifted over the drive sprocket this crack would open up and let loose crap fall out.....
