That's an interesting question. I'm not sure how you would pump CO2 into a bag and kill a colony. I'm not sure it's an accepted process for doing that. Maybe there's a chance you might accidentally euthanise yourself.

I imagine at the start of the process, he was hoping to just kill the queen, and the entire colony would survive. In that case the other bees would replace the queen, with an emergency queen cell, if this was to happen the queen would probably be as aggressive as the previous generation.

But he mentions that he intends on introducing a queen himself. In which case, I would have thought the colony would calm down.

But I have no idea how much by, because I've never been in this situation.

Put a big trash bag over the entire box, tie it up at the bottom, punch a small hole and put a hose from a cheap CO2 tank, ozone generator (also cheap), car exhaust, what have you?

If they were aggressive invasive bees wouldn't it make more sense to just kill all of them rather than replace the queen? Those aren't the sort of bees we want flying around our neighborhoods.

His method probably released hundreds of aggressive bees into the air everywhere , whereas if you bag it up they can't go anywhere.

Well, as he says in his video, it's typically the queen that dictates how aggressive the colony is.

Watching the video, he taped the hive up and then poured the soapy water in. I doubt that many were able to get away at all.

Those that were out foraging, would probably die pretty quickly without a hive to go back to.

Yes, the queen dictates the mood of the hive but it happens in 2 ways- her genetics, and her pheromones. It can take over a month before the mood of the hive would change after a re-queening. Even with a queen replacement, there are thousands of these aggressive bees already in there. With nearby kids and horses, and the incredible behavior of this hive, I don't blame him for deciding that the responsible step is euthanizing the whole colony.
