No, it's by design and clearly documented at least in russian 
docs.  Probably English wiki needs clarification here.

Basically, when you set array directive at certan level this 
clears everything inherited from upper levels for this array.  
This applies to other array directives as well (proxy_add_header, 
access_log, etc.).
