It looks like this works like Apple watch on iOS: there’s an extra security layer as the watch also has to be unlocked. Smart lock just requires a paired device to be within range.
An Apple Watch locks itself when you take it off, so if someone took your iPhone and Apple Watch from you they couldn’t unlock either device. I presume this is the same?
Edit: the article implies that this feature allows verification when you initiate the unlock, whereas Smart Lock actually keeps the deviced unlocked the entire time the paired device is nearby, which in practice is very different and less secure.
