Yes, this is as documented in the Ver 14.4 Release Notes: "List owners are now able to set the 'Sub-Lists=' keyword for the mailing lists they own, with the restriction that they can only set it to other mailing lists they own. This means that a list owner can set "Sub-Lists= TESTLIST1,TESTLIST2" only if the list owner setting the keyword is also a listowner for the TESTLIST1 and TESTLIST2 mailing lists."
