CumulonimbusYes this is expected behavior. Each GTM/DNS in a sync group needs to be able to communicate via iQuery with all other F5 devices configured, so all other F5 DNS/GTM devices and all LTM devices.
When using iQuery (bigip) to monitor other F5 devives results are not shared from one F5 DNS/GTM to others within the group as iQuery basically broadcast information so if all connections are working correctly no need to share data, also iQuery can contain a lot of information so you don't want to duplicate network traffic if not needed.
I know is because i asked the same thing a while ago on DevCentral, see the following link: GTM Sync Group, sharing state information
