No it doesn't.
There are two pictures (really three). Two of the pictures is the one I posted. One blurry, one
slightly less not. The other picture is a
screen-cap from a video. It too shows the noose that was pictured in the other pictures. It's not a double half hitch. Whatever you saw, wasn't this.
Of note, of the 29 tracks where NASCAR has a race, containing a total of 1,684 garage stalls, they found only 11 total ropes that had a pulldown rope tied in a knot, and just one noose (the one in Bubba's stall).
