Last I checked, it does. I'm pretty sure for instance the Nexus 5X relies on standard LUKS for FDE. What may be protected through other means is the key used to encrypt that filesystem. The user enters a pin or a pattern to unlock said key on boot, and that key is used to initiate LUKS. Maybe that's what they have cracked here?
