Need Help Analyzing Studies Mentioned in a Fitness Claim

I need some help from those who are good at analyzing studies. I came across this Instagram post that claims a specific exercise technique is superior for hypertrophy.

Around the middle of the video, the creator references three studies within a couple of seconds, which immediately set off my "smelling BS" detector. Here are the studies cited:

  1. Study 1
  2. Study 2
  3. Study 3

After looking at them, I can’t see how they support the conclusion that performing pushdowns this specific way, and in general having an ultra and excessive stabilized exercise is superior for hypertrophy.

Can anyone with a better grasp of study analysis help me out here? Is there any legitimate link between these studies and the claim, or is my skepticism justified?
