It is an example of an override occurring without the “override” keyword, and a demonstration that the “override” keyword’s purpose is to indicate programmer intent rather than do anything to the actual generated machine code (otherwise, the override here wouldn’t have happened). Despite this, no one argues against the existence of the “override” keyword.
