Why did Owen hart show how he died?

Owen Hart was wearing a harness before his death because he died from falling around 70 ft. into the ring. It was part of a stunt he was doing for his gimmick, The Blue Blazer. He was intended to descend from the ceiling in a superhero-like fashion, then trip once he landed in the ring. Unfortunately, the stunt malfunctioned and the harness came loose, and he fell into the ring, landing on the ropes, and died. The harness was to prevent something like this from happened, although clearly it didn't work out very well.
