Who knows why the video is gone. Could have been self deleted, could have been incorrectly flagged for copyright by a bot. Someone did save it but as you can see the recording is very poor.

This video just took existing edits and compiled them into one video (without crediting any of the creators of the original edits, yay)
No, that YouTube video is just a collection of these edits. These edits predate the video and I don’t think whoever made the video has anything to do with the person who made the edits.
