As I explained in my previous reply, is that the archive on s.b.o. was
generated before the hg backend was made reproducible. It now is.

Yes, see commit 76b51f90c0e; quoting:

    (The reason is that in the first case, a temporary file is created and
    then compressed, and gzip is adding the filename and its timestamp in
    the gzip header, while in the second case, there is no temporary file,
    and thus no timestamp and thus it is reproducible.)
