New Longest Table Tennis Rally - is this legit?

[Superdragon]

It was a ton of fun watching and supporting Dan and Llyod when the set the record at 13 hours, 36 minutes, and 36 seconds. It's officially recognized that this was broken by Swedish duo Emil Ohlsson and Fredrik Nilsson, who achieved a continuous rally of 13 hours, 37 minutes, and 6 seconds. However, I've seen news of Redrik and Emil aka The Spin Duo who had a rally of 15 hours, 43 minutes and 35 seconds.

Please see:

This allegedly happened on April 18th, but I just randomly came across it, and haven't seen official news about it, and don't see any new Guiness official recognition.

So, what's the scoop here. Is this legitimate, and will it be officially recognized as a new world record for the longest table tennis rally?

Edit - the duo mention the new record on Reddit:

I actually stumbled across the livestream while they were doing this and noticed they were past Dan's time already haha
