The top of the cowl are frequently used as the upper side of a cooling 
plenum on air cooled engines.  A seam there might make it harder to prevent 
pressure loss.  Esthetics might play a part, looking through the window 
shield no seam shows.  I can't think of any structural or aerodynamic 
reason - not to say there might not be some, but I can't think of one.
