It can add some security, especially against most opponents that are not
going to bother to try to fake the print.
For example, four fingers, scanned either upwards or downwards gives you
8 'keys'. If you add a 90 degree rotated finger, that gives you 4*4 = 16
And as the sensors are typically designed as a 256*4 or so camera, you
can basically do an optical mouse with them, in reverse, using the
finger as a 'surface', to add gestures in the middle of the prints.
