You mean IF SYNC is turned ON , then RE will advertise only if all IBGP have learned about the NET
and what about RB at that point will it also have to wait before adverstsing
" When an AS provides transit service to other ASs and if there are non-BGP routers in the AS, transit traffic might be dropped if the intermediate non-BGP routers have not learned routes for that traffic via an IGP. The BGP synchronization rule states that if an AS provides transit service to another AS, BGP should not advertise a route until all of the routers within the AS have learned about the route via an IGP."
With the current scenario, Assuming no router reflectors are configured, and without any type of filteration in router B, Then AS 65000 can Only recieve routes from (Router B). Router D Can also advertise Networks to Router B and then to AS 65000 IF and Only IF the networks are originated from Router D itself.
