The idea being that you are able to disable the biometric stuff before you expect to encounter a situation involving overreaching law enforcement. Hitting the power button 5 times in your pocket is easy enough. Additionally TouchID is disabled after several hours of the device being unlocked. I presume FaceID is no different. So if you refuse to comply and they have to get a court order then the time limit may be reached. You can even have the device wipe itself after 10 failed attempts to unlock it.
