filter - Is there anything wrong with the Nginx rule I wrote?

Question

if($server_name = fonts.xmap.org){
    sub_filter 'fonts.gstatic.com' 'fonts.xmap.org';
}else if($server_name = jfonts.xmap.org){
    sub_filter 'fonts.gstatic.com' 'jfonts.xmap.org';
}

Kneel down and beg the great god to explain. . .
