cron: why not?

[Martin F Krafft <madduck@madduck.net>]

30 7 1-7 * 0 /home/madduck/mirror/mother/do_backup -x
30 7 8-31 * 0 /home/madduck/mirror/mother/do_backup

am i right or not, this should run do_backup with the -x argument only
every first sunday of a month, and otherwise just do_backup without
arguments every other sunday? the -x version just ran this morning...
why??

i though saying "run on days 1-7 if day of week is 0 (sunday)" does
not include thursday, september 6...
