Not really the same concept, the cupping isn't due to too many left or right turns, some cars just cause the tire to "cup".

My Tahoe for example, I need to ensure the tires get rotated, if I don't I'll see the inside edge of the front tires tread starting to wear with a "cupping" look. I've had the alignment checked and all is fine, it's just how it wears the tires.

If I keep the tires rotated, before the cupping is noticable, then I get better wear from a set of tires.
