Skora's done it several times, but there is a video of him doing aeatw in a show where he did this. He caught the ball once, twice, tied his shoe, then did aeatw. Killed the flow of the show, and unfortunately the crowd doesn't really understand how difficult aeatw is.
I just think it looks ugly. It's ok to do when you are practicing if you cut it out of the video. I have no idea what the editor was thinking leaving that in the video. I just don't think you should do it in performances either, because it kills the flow of the performance. Also, in many competitions this should technically count as a drop. Unless hands are period allowed, it should count as a drop as it's not a trick.
Obviously, Skora and MP are amazing freestylers, so it's nothing against them. It's just one thing that could be improved.
