Watching older Youtube Live Streams

I just noticed the following Youtube livestream:

https://www.youtube.com/watch?v=DPfHHls50-w

which is of a Falcon Heavy launch which happened 9 days ago. Despite that, it still is marked as LIVE and I cannot jump forward in it. There are also people posting comments with timestamps which are in realtime now. I thought that usually livestreams turned into normal Youtube videos after they completed but this is not a normal video.

Am I watching an old livestream from 9 days ago which is somehow "repeating" or is this "false advertising" and claims to be live now but is actually re-streaming the previous event as if it were happening now?

Thanks!
