While there still is a large amount of blood lost, which you can see not only running fresh on the pavement from the wound, but also dried blood is surrounding as well and leading away from his body towards where the truck came to rest. I can only assume that there is a lot of blood still left in the legs, which would not bleed normally since there is no longer a heart connected to those parts of the body thus there is no longer a force to pump to blood out. Needless to say the victim lost the majority of his blood when his legs left him considering the amount of blood that would be in them, so there's not much for his heart to pump out of the upper half of his body, just enough to keep his brain supplied enough with oxygen to stay conscious. Another possibility I suppose it that the friction and heat caused between the tires and the road could seared some of the would/blood vessels closed as it happened :dunno:
