Hi DjangoReinhardt!
Good question; I can answer this one...
The site uses html5 to pre-render pages to improve the user experience / site performance... Part of this includes storing the query parameters you make (when running a query) in the new HTML5 web-storage.
This allows the webpage to be rendered before the user actually clicks the "submit" button on any of the tools (Making the site load faster it would normally). The query you specify is then pulled out of the HTML5 web-storage (when the pre-rendered page is made visible) and sent to the backend API servers.

Hope this clears this up for you :)
