Basically this tells it that eHow's Spark was already loaded so when you click on the button in the toolbar it refuses to load it, it's dead, defunct.
This method could probably be used to stop any tool loaded in a toolbar without mucking up the meta tags. The only issue is it's not a supported method by the vendor so they can change that variable sparkLoaded to something else and it won't work, but it's an easy cat and mouse game to keep on top.
FWIW, that was much easier than my last frame buster script!
