The $server_name variable is always first name as defined by the 
"server_name" directive in the server{} in question.

With default fastcgi_params as shipped with nginx, SERVER_NAME as 
passed to php via fastcgi will be set to $server_name, i.e. first 
name defined with the "server_name" directive.

Yes, this is correct and expected behaviour.
