The motors are reversible shaded pole motors. How could that be, you

Energize one motor and it runs clockwise, energize the other winding
and it runs counter clockwise.

Actually, it's quite simple to design a shaded pole motor with two shading
windings that can be switched for direction change. Just never seen it
commercially.
