It is designed that way. It realizes that by defining a roll to level and +5G climb as a successful recovery, and preventing the aircraft from being flown into a condition where a successful recovery is impossible. So if you're flying right above terrain and you suddenly fly down, the airplane should accept your inputs and fly towards terrain until the moment recovery is impossible and will then engage. This video from the Air Force shows this clearly: https://youtu.be/Wf27X73jxlE?t=144 https://youtu.be/Wf27X73jxlE?t=144 The system allows you to fly low and fast (2300 feet above ground and 500 mph) until a +5G pull wouldn't get you off the ground, then activation.
