   I've got confused between these 2.   
      
   If it really is twisted - then there's no way that they share the same North &   
   South; meaning N & S should be twisted as well and "walking along the North"   
   you end up getting to the South & back. AND also it should be at least dual   
   sided, because you'd    
   get to the "other side" after a twist...
