Yes, there is more wrong than right what that whole setup.
Casting on a bench top to begin with isn't the brightest idea, you place your mold in the center of a concrete floor and you cast with something long enough to keep you safe, and you wear heat resistant aprons instead of lab coats. They got off very light, fortunately. I hope that they also realize they're out of their depth in the education department, because by showing this stuff to others when it does work they are passing on a ton of bad practices.
The same goes for a lot of videos and articles about home made batteries. I think I spent more time and effort on safety while doing my battery build than I did on the actual building and I'm pretty sure that if I had not that I would have had a real problem.
But casting metal and welding are still far safer than working on large Lithium-Ion packs in my opinion.
