Hate to burst your bubble, but the way all constrictors kill tells you a different story. The prey is always secured by a bite first, then constricted. All constrictors prefer to swallow prey head first, and since they all have recurved teeth, they cannot easily release their bite, so it is very unlikely the snake grabbed a leg. Current thought is death is by circulation restriction as opposed to suffocation, still a minute or so to unconsciousness and death.
Odds are, if this is real, the poor bugger was grabbed by the head, painfully, prior to constriction starting, and his last memory would be that of python breath.
A python will strike and bite its prey on any part of the animal's body. They don't specifically aim for the head.
Primarily, the snake is attempting to quickly secure and subdue its prey. For most pythons, a sense of "smell" and heat detection provide the primary stimuli for identifying prey and focusing the strike, with visual cues such as the movement of the prey a more minor stimulus. A python most likely targets its bite at where it perceives the strongest sensory signals, rather than any specific body part of the prey.
Despite the recurved teeth, pythons (and other snakes) are satisfactorily adept at repositioning themselves and their prey to commence swallowing their prey headfirst. They generally do this in one of two ways.
The snake will either simply release its bite (the gape is expansive allowing teeth to disengage) and then "sniff" and nuzzle the prey until it finds the head to commence swallowing. Or the snake may reposition its bite by incrementally and alternately moving its own head/upper jaws and each independently articulated lower jaw bone toward the head of the prey.
Large pythons like Retics and Burmese become less arboreal as they become larger and heavier, so it's most probable that the snake was on the ground (or close to it) and most likely initially grabbed the man's leg or lower body.
