Group Owners are indeed exempt from this (and other stuff), if they are set correctly. It's not an issue of Owner/Mod vs Member, it's the way the individual's person setting works, the system just does its thing as it's supposed to do without caring if you are a mod or member.
You have your owner account set to "group default setting", that's why this is happening.
Change your owner (and mods') setting to "override: can always post", and your problem will go away. That will also bring you closer to admin "best practices", as one should always want their admin stuff have all the power they need AND exercise it without any hindrance.
