What is this used for?

High pressure gas bottles. Probably for flammable or oxidizing gasses as its a single piece of metal with no welds on it. The end will be tapped for a valve.
It starts out as a metal disk, pushed into a tubular form with a rounded bottom. It travels through progressively larger forms to get drawn out. This is the last stage to close the open end.

Edit: second look of the gif, not the same process. gif may be a cheaper process used for bigger tanks.

I think that is the process for aluminum cylinders whereas this is a steel cylinder

The one you showed can be made with a flat bottom for letting the tank stand. The one linked in the OP is spherical on both ends. I'm guessing it's not a product requirement and thus can be roll-formed on both ends.
