Oh, sorry. I should have explained that better.
YouTube allows users to make their videos public, private, or unlisted. Unlisted videos are like public videos but won't show up in YouTube's search results. Some of the major official accounts, will have some of their videos unlisted to avoid cluttering up their channel (e.g. a band having their many live versions of a song, unlisted). Unlisted Videos is a site for making those unlisted YouTube videos, easier to find.
Anyone with access to the URL, or a webpage with the video embedded, can access the video.
Those particular WWE videos are unlisted, but there may exist unofficial replicas or trimmed/edited versions of them elsewhere. An unlisted video will have a grey padlock icon on the YouTube page. For example, the Zeb Colter and Jack Swagger explain the concept of fiction to Glenn Beck video:
