Is see it as delibrate act from Mario.. a few things just don't add up
1. When regaining balance you dont accelerate your foot to the floor, you look to cushion yourself if anything..
2. his momentum is taken him in the opposite direction by doing what he did would only make him further of balance..( If he was that off balance.. I dont think he is that he was before the stamp)
3. he knows parker is there as he has just accidentally stepped on his hand and parker has fallen against the back of his legs..
4. The dive at the end to try and divert attention away from what he has done
