The guy is a beast and has conditioning dialed in, and his MUSCLE proportions are excellent, but FF is right, his height/limb proportions are unusual and not ideal.
Most guys have a wingspan that is longer than their height. White guys usually ~2", black guys a bit more. From the photos of this guy, it appears his wingspan is barely his actual height (if that) giving him "short arms".
Additionally, his legs are a smaller percentage of his overall height compared to the average athletic male, especially compared to some of the most popular bodybuilders such as Arnold or Ronnie who had very long legs compared to abdomen length.
Finally, the first photo is a bit of an illusion - his hips are pushed back quite a bit, maybe more than normal for a FDB, giving the illusion of an even longer torso and even shorter legs. You can tell that picture really accentuates the short arm effect, because it truly looks like if he put his hands straight down, his fingers would barely touch his iliac crest.
His limb proportion is close to the opposite of Arnold, who had long legs vs shorter torso, with long arms.
