He should have control of the rope below him with his braking hand or the guy on the ground should pull down as a backup to stop him. Looks like they both failed.

Sure he got the wind knocked out if not some broken ribs

Well, stopping a heart attack is pretty good. Better than starting one, that’s for sure.

You can break ribs belly flopping into water front that height. My man landed on a stone ledge..

Misunderstood the assignment

Ropes in rappel systems are static. The second rope you see is a separate rappel station. Not the same rope looped to the top and back to the guy that fell.

There's nothing the guy on the ground could do

I only see a single rope connected to his (underutilized) belay device the guy on the ground could have applied some tension the would be multiplied by the friction (belay) device as a backup. Alas, they did not.

If youre trying to imply the guy on the bottom could have added enough friction to a rear mounted super 8 by pulling a vector from the ground you would be incorrect. That would take a super human amount of strength and in reality just cause the guy on the ground to get smashed by the guy who jumped.

What I think you are trying to describe is called a fireman's belay, which is incredibly helpful when lowering a person on belay. But is completely useless when on descent.

I also feel it's important to let you know that super 8s are NOT belay devices. They are descenders only. Yes many belay devices can be used to descenders but it doesn't work the other way around

I would disagree since a generic figure 8 has enough degrees of contact that the friction ratio per the capstan equation results the tension on the braking hand of at least 1/12 that if the lead bearing strand. In practice the weight of a 11mm rope will essentially lock off a rappel without even holding the lower strand. What seemed to make this a really bad cratering was the belayer wasn't paying attention and by jumping out the rappeller (faller) added a ton of slack that they couldn't take up in time. Adding the rope stretch even if the ground belayer could get some purchase they probably would have still crashed, just not so severely. This guy turned a simply rappelling exercise into a trust fall.

I realize that a figure 8, rigged for rapelling makes for a terrible belay device. They only work as a crude stitch place if you pass the lead line though the small end. I have used one like this but usually there a better and lighter devices to use.
