Rear shoulder belts in Duster?

Ok, that part I get but would you not end up with two male buckle ends trying to plug into one female end? because on a regular shoulder belt it is one continuous loop that has only one male end, sorry I am a visual guy and just cant seem to visualize this but I am thinking that there are three parts here, one that comes down from the parcel tray with the dog bone holding it up, one bolted to the floor at the side of the seat, and one in the middle of the seat that latches it, am I wrong? if so and its only two pieces then that's where I'm lost.
