There is nothing automatic about the ordering of contributions on a workpage - the new uploads are first at the bottom of the page.
There will be a moderator who will have to do the copyright review and will clean up if necessary within the next 6-12 hours.
However, if you are more adventurous, you could open the edit window and do the cleanup yourself. Not knowing anything about wiki-code and usually forgetting about it immediately, I personally found it very helpful to open another page with a similar content in the edit window too and just copy the relevant parts over. Just beware of those curvy brackets - just missing one of these and you may wreck the layout of the entire workpage - and always check with preview that nothing as sinister as that has happened.
