The documentation quoted upthread states the argument is named BUTTON.
It is easy to conclude that the action function, when called, will
receive as its argument a reference to the button object that was
clicked.

This pattern is widespread in GUI frameworks. It lets you create a
bunch of slightly different buttons and assign them all the same
single action, and it will be able to do slightly different things for
each button.
