This is what first came to my mind as well. But I also reacted to Ars Technica reporting[1] that the sensor has the capability to scan "sub-epidermal skin layers". That might be a way to protect the system from the fingerprint "copy-paste" method described in your link, since the sensor used there only scans the surface.
