From an electrical engineering perspective, that article is
wrong (and it shows how guys like Lew can get confused on
the subject).

All of the motor designs shown there, except for the shaded
pole motor, are split-phase motors. Any single phase motor
with a starting or auxilliary winding is a split-phase motor,
because the phase of the starting/auxilliary winding is not
the same as the main winding. That's why they're called
split-phase motors, because they have two windings with
different phases.
