I don't believe this is true on iOS, unless there was a recent change I'm not aware of.
Right now, tapping power five times on my phone running iOS 16.1.1 opens an "emergency" mode, which allows anyone to call 911 or see my "Medical ID". It also has an option to "cancel" this mode, which returns the phone to a normal locked state but forces a passcode to unlock (i.e. Face ID will not unlock the phone in this state).
