Indeed, I was following what file-remote-p says itself:

    Tip: You can use this expansion of remote identifier components
         to derive a new remote file name from an existing one.  For
         example, if FILE is "/sudo::/path/to/file" then

           (concat (file-remote-p FILE) "/bin/sh")

         returns a remote file name for file "/bin/sh" that has the
         same remote identifier as FILE but expanded; a name such as
         "/sudo:root <at> myhost:/bin/sh".
