Real world explanation would be that it's a very common punch in MMA due to the use of level changes (and MMA angles..) and it's a devastating blow most of the time.

But in-game... it's a straight up trash. Now that you've mentioned it, yeah a lot of fighters got that lately and I wouldn't even be surprised if Wonderboy or Artem got them..

Though you can master the timing down for each fighters depending on their reach AND their opponents' reach. I posted a more detailed reply on Power Overhand and Power Hook thread. Do check it out.
