You're missing something.

You're either missing that if the second argument to add_header expands
to empty, then the header is not added; or that configuration directive
inheritance is by replacement, not addition.

==
  server {
    listen 8080;
    add_header X-Server server-level;
    add_header X-Surprise $http_surprise;

    location /one {
      return 200 "location one";
    }
    location /two {
      return 200 "location two";
      add_header X-Location two;
    }
  }
==

Compare the outputs you actually get from

  curl -i http://127.0.0.1:8080/one

  curl -i http://127.0.0.1:8080/two

  curl -i -H Surprise:value http://127.0.0.1:8080/one

with what you expect to get.
