re-route with optional argument. possible bug??

http://localhost/<project>admin/foos does link to $route ["admin/foos" ] = "admin/hello" ;(which is not define in route) and i think will not link to
$route ["admin/foos/(:num)" ] = "administered/hello/$1" ;

The problem is that even though the parameter is optional, the route

PHP Code:

$route["admin/foos/(:num)"] = "admin/hello/$1"; 


should still behave as

PHP Code:

$route["admin/hello/(:num)"] = "admin/hello/$1"; 


simply calling urls 

Code:

http://localhost/<project>admin/foos

and

Code:

http://localhost/<project>admin/hello

should show same result.
