I know gymnasts are trained like the guy in the link below, but is the summersaults necessary and why?

They aren’t not “jumping higher” if your definition of height is “height above ground that the center of mass of the object is moved”. By doing a somersault the “lowest part” of the body i is brought closer to the center of mass, thereby giving the appearance of gaining more height. It is true that this person would clear a higher object, but not as high as someone doing an even more optimized method like the fosberry flop in high-jumping. For the video he get a long limb higher because he extends it out from the center of gravity. He is not however getting his center of gravity any higher.
