Loops in the route are not possible without custom RoutePartHandlers.

Yes, the "magic" lies in the method findValueToMatch() which you can 
override. It receives the complete rest of the request path (e.g. 
"cat1/cat2/cat3/foo.html") and you can return everything that belongs to 
your route (in this case "cat1/cat2/cat3").

Then, in the matchValue() method you'll receive that part and can post 
process it.
Just make sure that matchValue() and resoveValue() are deterministic and 
that you are not allowed to return objects.
Also have a look at the NodeRoutePartHandler of the TYPO3 package [1] - 
it's responsibility is to turn a request path into a TYPO3CR node vice 
versa.

Please let us know if that helped,
Bastian
