Samsung previously explained the problem by noting that the ultrasonic fingerprint was mistakenly “recognizing 3-dimensional patterns appearing on certain silicone screen protecting cases as users’ fingerprints.” As a temporary solution, Samsung recommends that users either remove the problematic screen protectors in question and reregister their prints or use a different authentication method (like a regular password) until the patch is released.
You keep using that word, "explains". I do not think it means what you think it means.
