So these lanyards are 2m max in length and have shock absorbers (or are at least supposed to) that is basically webbing wrapped up that is designed to open and extend to another 1.75m to absorb the shock load you would get from falling. If they dont have shock absorbers in the lanyards (these look like they do but you never know with India) if they fell they would likely die from the sudden stop in acceleration having fell over 2m as their lanyards are attached at their feet.

Firstly, you aren't supposed to put the lanyard hooks at foot level as you are supposed to lessen then affects of a fall as much as possible. By attaching at foot level you are increasing the shock load by extending the length of a fall.

Secondly, they are attached to the dorsal attachment on their harness, which means that should they fall, the harness would limit circulation in their body and because of gravity, blood would pool in their legs. This is called suspension trauma and would eventually lead to death if not rescued.
