The video says you can't just mirror it for left handed people, still need it to spin the same direction. Do you know why? Isn't it symmetric?

On a feathered shuttlecock, the feathers aren't symmetric; they overlap in one direction.

Might be possible on a plastic shuttlecock, though.

Not on a feathered shuttlecock, the feathers overlap in a pattern. Curious if it works with a plastic one.
