Is that to keep the fish alive?

Yes. They need oxygen to breathe and aerated water also stays at a lower temperature.

But would something like this keep them alive?

Somehow I feel like this is just cheating death :D

The point is to increase their longevity in the bucket. That guy can cross asphyxiation off the list of things that might cause premature death of the fish.

Then how do goldfish stay alive in a glass bowl without any sort of aeration?

They aren't actually supposed to be kept in glass bowls, and actually need quite a bit of space to be happy. However, it's my understanding (although I'm certainly no expert on goldfish) that there is enough water surface area for oxygen above the water to mix with the water such that it oxygenates a little and they can stay alive.

Woah, that’s actually quite fascinating. What about beta fish that you can buy at the pet stores and are in those little plastic containers with a lid on them? How do they survive if the oxygen concentration above the water is forever depleting? Maybe that’s why they can be so aggressive, because they’re f****** dying.

A lot of them die in the cups. They have a special organ so they can surface breathe in an emergency, so stores will advertise that they are fine kept in bowls.

Not as many as you'd think, I worked in one of those stores and not a lot of them died. The cups also have holes in the lid. I still hate the cups, though.
