Yes, the bypass doesnt work after a fresh reboot. On a device that was atleast once unlocked after boot, it works no problem.

According to his blog it also works after a reboot and that's how he found it. He later found the reboot wasn't necessary. This made it more dangerous because you need less time to get in.

Depends on what exactly works. The lock screen dismiss works everytime, that's true. But its of any use only if the device was previously unlocked with PIN/password after boot. Otherwise the phone is still encrypted and bypassing the screen is useless(you can't access any user data)

That's not how I read this: they started from an unlocked state to get passed the fingerprint unlock screen. Did I miss something?

When a phone is rebooted, a password must be entered before touch id or face id will work.

In this context, "unlocked" doesnt mean you start from the home screen - it means the password was entered at some point since the phone was last booted up and is now in an unlocked state where touch/face id can be used.
