As far as I can tell it's typically used to enable/disable buttons in a editor UI, while you move through the text. Having queryCommandEnabled('copy') return true only during click event processing would for a typical editor make the "copy" button enabled only while you click in the document.. It would take some special-casing and logic to work around that.
