Why is root not overridden in nginx?

Question

Nginx

there is a pretty simple config for nginx

server {
        listen 443;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_ciphers ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM;
        ssl_session_cache   shared:SSL:10m;
        ssl_session_timeout 10m;
        ssl on;
        ssl_certificate /var/www/certificate/SSL.crt;
        ssl_certificate_key /var/www/certificate/mydomain.com.key;

        root /var/www/mydomain.com;
        index index.html index.htm index.php;

        error_log /var/www/error.log;

        location ~ \.php$ {
                fastcgi_split_path_info ^(.+\.php)(/.+)$;
                fastcgi_pass unix:/var/run/php5-fpm.sock;
                fastcgi_index index.php;
                include fastcgi_params;
        }

        location /front/ {
                root /home/someuser/front/deploy/current/public/;
                try_files /$uri /dist/index.html;
        }

Request https://maydomain.com/front returns 404
I assumed the search would be in /home/someuser/front/deploy/current/public. But the logs say:

2016/02/13 20:11:52 [error] 20775#0: *18 open() "/var/www/mydomain.com/dist/index.html" failed (2: No such file ordirectory), client: ***.***.***.***, server: , request: "GET /front/ HTTP/1.1", host: "mydomain.com"

I tried to write alias instead of root, but the result is the same.
Why doesn't the main root overlap?
