The gravitational forces are strong enough for their fingertips to absorb, but adding horizontal motion that they also need to cease is making the grab almost twice as difficult. I have tried the jump on a replica and can say you are only partially right there. If you are heavy and muscular a higher jump can diminish the force of impact because your forearm will be more angled on impact and your muscle absorbs the impact kind of like a suspension. But for this to work the muscle must remain rigid, flexed and somewhat angled after the swing which is very hard to do. (try holding a barbell while flexing the biceps and drop the weight you will immediately lose tension in the muscle) (the angled part is the most difficult as you instinctively reach and stretch out the arms to grab) For a lighter person higher jumps are not necessary, instead landing at a certain diagonal angle with the legs not too far behind the obstacle seems to be the key The higher you jump the wider your margin of error for landing with your hands at different height levels, and since you jump sideways it's important to jump over the right shoulder if you are right handed because it will be the hand that is slightly higher and slightly stronger (therefore using the opposite hand for the final kick and first impact) This obstacle is tedious to train because you can't simply do it again and again (a great temptation after you built it) It's very easy to get tendinitis from this

The way you describe it definitely makes more sense to me. And yes, a lot of shock to your forearms like this can be really bad for your tendons. Same with really high jumps!
