Two servers with the same server_name. This is fine?

Question

Nginx

Hello.
In one config (/etc/nginx/vhosts/www-root/site.com.conf) I have two server {} for the same domain as in the first one:

server {
  server_name site.com;
}

What's in the second:

server {
  server_name site.com;
}

The body of the server itself does not differ much, there are 5 different lines ... The config is managed using the ISP panel. I think why two servers for the same site, with a slight difference. Is this how it should be? Or should both servers be rewritten into one?
Thank you.
