This is not completely true. The AI will check only if there is already a facility present in the system with the system wide ability but ignore facilities under construction. Therefore several identical system wide facilities may be constructed at the same time and eventually present in the same system. I see this all the time.
A possible solution would be a special colony type that is only chosen once per system and then put all the system facilities on this colony.

I usually use different method: diversify colony types, using planet size as a criteria. For example I usualy have several mineral mining colony types with different order of facilities for tiny, small, etc. planets. There' still a problem with non-breathable planets but I arange system wide facilities that they can be build on breathable planets only.
