Shouldn't this trigger an nginx 404?

Besides "fastcgi_intercept_errors on" you also need

     error_page  404  /404.html;

nginx does not intercept an error if there is no custom handler for it:
it does not show its default pages. This allows to intercept some errors,
while passing others as are.

Also, two ways to omit rewrites:

                 location / {
                        try_files  $uri  /bar.php?slug=$uri;
                 }

                 location ~ ^/files/(.*) {
                         fastcgi_pass 127.0.0.1:11021;
                         fastcgi_param  SCRIPT_FILENAME /foo.php;
                         fastcgi_param  QUERY_STRING    file=$1;
                 }

                 location ~ \.php$ {
                         fastcgi_pass 127.0.0.1:11021;
                         fastcgi_param  SCRIPT_FILENAME /path/to$uri;
                         fastcgi_param  QUERY_STRING    $query_string;
                 }

or

                 location / {
                        try_files  $uri  @bar;
                 }

                 location ~ ^/files/(.*) {
                         fastcgi_pass 127.0.0.1:11021;
                         fastcgi_param  SCRIPT_FILENAME /path/to/foo.php;
                         fastcgi_param  QUERY_STRING    file=$1;
                 }

                 location @bar;
                         fastcgi_pass 127.0.0.1:11021;
                         fastcgi_param  SCRIPT_FILENAME /path/to/bar.php;
                         fastcgi_param  QUERY_STRING    slug=$request_ur;
                 }

                 location ~ \.php$ {
                         fastcgi_pass 127.0.0.1:11021;
                         fastcgi_param  SCRIPT_FILENAME /path/to$uri;
                         fastcgi_param  QUERY_STRING    $query_string;
                 }
