Maybe author isn't an iOS user because that message appears if you don't use your iphone for 5 hours — Touch ID (and Face ID) tokens are zeroed after five hours in non-use state and you have to enter passcode to reenable the security feature. I bet that was the case on stage.
Not sure about this. My iPhone 7 Plus works straight without seeking Passcode using Touch ID, in the morning after being unused for the entire night (more than 5 hours).
