I feel like you're conflating "sampling rate" with "tight feedback loop". Yes, a higher sampling rate (assuming each sample remains at or above the level of quality of your lower rate samples) is always better. But a tighter feedback loop is one where you are making decisions with that data at a faster clip too. As pointed out in the article (and by yourself), this is not always good. If you are using some averaging filter, as you say, then that is being "looser" about your feedback loop. You are recognizing that just because the accelerometer is telling you that you are going down doesn't mean you are about to crash. Someone with an overly tight feedback loop would not be so careful, and might immediately course-correct as soon as they sense they are going down unintentionally.
