I think that's a fair statement. What struck me about the video, was how artificial Jackson's face appeared. It's evocative of a guitar player who goes by the name "Buckethead". He wears a white plastic mask, with a KFC bucket on his head. But, the pallor and stillness of the mask is eerily similar to what pretends to be Jackson's face.
Dead man dancing. My guess is that the exertion wiped him out.
