To me, it sounds like more moving parts and trying to look for a problem that doesn't really exist (IMO). However, if it really gives more than 10% better range, that makes it worth trying in the real world.
My take on this is that there are multiple motor winding stacks (up to 4) and the controller manipulates the configuration of the stacks/windings (the number & posisition of motor poles) to achieve the best operating scenarios for starting, excellerating, cruising, decelerating, etc.
Unless your including the cooling system there shouldn't be anymore moving parts then present day motors (the two motor bearings).
However the controller will be more sophisticated bringing with it a greater chance of failure as likely there will be more components in the controller.
A 10% increase is great but if it comes with the need for fluid coooling it may not be advantageous for all applications.
The holy grail in the advancement in EV's will be the next generation of battery's with 2-3x increase.
EDIT:
Forgot to include that the controller will also configure the motor phase (1, 2, 3, & even 6) for the best output for a given condition/situation.
Also upon watching the video, it appears that some of the the magic occurs in the rotor & thus perhaps commutators would be needed.
