Not quite! If you have an attribute "onclick" and set the DOM property "onclick", the attribute value stays unchanged, but if you click, the function set by the property gets called. Set the attribute an both the attribute value and the DOM property change - the latter to a function as described in the original article.
Think of the actual function that gets called as residing in an internal slot on the element. Both the attribute and the property can set the slot's value, and setting and the DOM propertie's getter accesses the slot directly. Sort of, if i remember correctly.
