This clip is not "from the last weekend" as he says, but from the last year's 2023 "Exercise Patience" Regional Convention - Last talk of Friday afternoon session, given by the branch representative.
The speaker in the convention is simply explaining Matt 25:31 and saying that Jesus will sit on his judgement throne to separate the sheep and the goats in the future, and not in 1914 as once thought.
The creator of the video is just getting confused with the semantics about Jesus becoming king in 1914 vs. sitting on his judgement throne in the future during the great tribulation.
