why does user list member different lists in the two cases? same uid, same gid, only the lists it members are different.

Because Mailman is run by a server which was started as root and which then setuid'ed down to a lower privilege level.

You need to fully understand how Unix UIDs are managed for processes. I recommend any of the standard security tracts on why services that run as root and then setuid to something less privileged are less secure than those that start at the lower security setting.
