Бага или фича? if and try_files

[Андрей Василишин]

Есть такая конструкция, с включенным if, перестает работать try_files.
if заменили на двойной map, но все же хотелось бы знать это бага или фича?

location ~ \.(3gp|avi)$ {
	root /var/www;
         try_files
         	/site.com-st4$uri
                 /site.com-st6$uri
                 /site.com-st5$uri
                 /site.com-st3$uri
                 /site.com-st1$uri
                 /site.com-st2$uri
                 =404;
                 aio on;
                 directio  4k;
                 directio_alignment 4k;
                 output_buffers 1 2m;
		if ($http_user_agent ~* Wget|DVGet|Download){
			limit_rate  128K;
		}
}
