If that were true, I'd have been called 31 times by now. Plus the one year hiatus doesn't apply to different courts (petit vs grand for instance).
I can't speak for your state, but that is absolutely true in California. Perhaps there are enough do-gooders where you are that they don't need you every year?
But it is absolutely true; those who respond get called back soonest, and those who don't eventually stop getting summonses.
