Talked to F5 Support and confirmed this is by design.
The LTMs send (F5 Support said "broadcasts") status/monitor updates to all GTMs via iQuery, if the iQuery connection fails or is missing for the bigip monitor timeout period then the GTM will mark the LTM (server) down and all associated Virtual Servers.
Shaggy is correct you can use other monitoring for the Virtual Servers which can be delegated to another F5.
Not how I originally understood GTM sync group bigip monitor communication to work but I have been educated :)
