In fact: Defrag a SSD is ... useless. As the random access time is the same wherever the data is, the fragmentation has no effect.
And: The Flash memory cells of an SSD have a life time in terms of "switch times" (O to 1 ... 1 to 0). Defrag may accelerate the usure of the memory cells.
SSD have a controller which move data on the less used zone... Then a defrag software will break all the work of this controller.
Defraging an SSD is not a good idea
So for this vidéo, they certainly mde it for the fun and just ofr the perf time of defrag 6TB in few seconds (try this on a 6TB HDD.. and take a long break!)
