Yes, but the point here is that the first event is unobservable and thus not worth considering.

That is extremely incorrect. If for example we know for sure that the observations we've made so far lead to supernova explosion in 10 years and thus the resulting life-threatening gamma burst reaching Earth in 2028, it would make sense to do something before the actual "observation" of the burst.
