Actually, it simply strips away the files from the existing tarball, and
renames it(s copy) to match the usual expectations.

You need to explicitly use the --repack switch if you want a repack
(unless the original is not a friendly format, e.g., ZIP):

  uscan --repack --compression=xz

Maybe the text in uscan(1) comes from an earlier implementation, and
the text within parenthesis:

    --compression [ gzip | bzip2 | lzma | xz ]
           In  the  case  where  the  upstream  sources  are
           repacked (either because --repack option is given
           or  debian/copyright  contains  the  field Files-
           Excluded) […]

should be changed to something like: 

                    (either because it is a zip file or because
           of --repack)

(and ditto in mk-origtargz(1)).

Regards

David
