Yes, they do.
From the link I gave <http://developer.apple.com/mac/library/documentation/cocoa/conceptual/LowLevelFileMgmt/Articles/FileManagementNSURL.html>:
"File reference URLs provide a way to track a file by its ID. This means that the reference is valid even if the file’s name or location in the file system changes."
File reference URLs are new with Snow Leopard. Check out the release notes and "What's New in Mac OS X: Mac OS X 10.6" to learn about them.
And FSRefs have always had this property. Adding file reference URLs was essentially a way of allowing URLs to provide analogous functionality as FSRefs.
