OK, I played with it in some image resizers. It appears to me that it's just the angle you are seeing it from.
I seem to be able to make out a center bracket going down under the front bumper to a receiver hitch (like in the pic above in post #8), as I seem to be able to make out it doing the L.
I think you may just be seeing the passenger side strap going to the tow hook, and then the center support...and from the angle it may look like the driver side strap, but you can't see it really at all.
So my opinion is, it's like the one in the pic I previously posted.
Maybe someone with better software can confirm or refute.
