Aren't these both part of the same process? Whatever is being done to force that piece of aluminum into the correct shape, it involves the same piece of metal.
Sort of, the can's bottom is flat (potentially with specific varying thicknesses) after the drawing. A punch then shapes the bottom to what it needs to be.
