Dear Pieter,
  We were very curious also (only the first run had this feature, we had this 
area of the roof tool welded and recut with the door guide only to the right).  
The only cars I have ever seen with door guides to both side used two doors, 
either as an autobox, or a ventilated boxcar.  I always wondered if a 2nd door 
would someday be added to the cars for ventilation similar to the ACL 
watermelon cars...
