According to the analysis presented here, equator and the parallel of 64°N have mathematically identical outcomes. Even though the rotation provides much more angular velocity at equator, special things appear at 64°N as well.
Some would just show some reflex and start talking about something else, but there is a reason for this.
The division lines between mantle convection rolls have a long term guiding effect for the tectonic drift, leading to these results.
