The meaning of two proxy_pass directives

I saw some nginx configs written like this:

location ~ {

proxy_pass http://upstream1;
proxy_pass http://upstream2;


What this config meaning? proxy_pass to upstream2 if proxy_pass to
upstream fails?

sorry. typo.
proxy_pass to upstream2 if proxy_pass to upstream1 fails?

This is a wrong configuration, as well as

 location ... {
      proxy_pass    ...
      fastcgi_pass  ...

nginx currently does not report this is as error.

so what will happen if config like this? Only the 2nd proxy_pass takes
