While I agree with you in principle, and echo your sentiment, it appears to be unwarranted in this particular case. That looks to be 4 separate gif images up there, and likely split up because the person creating the gifs chose specific parts he/she wanted to highlight, which didn’t happen to follow each other consecutively in the original video.

Or would you want the image to have all 4 highlighted parts edited together into one longer gif? That might make it a bit jumpy to watch.
