Your assumption was wrong. The problem is simple: you can't use
contexts as long as stored data must survive internal
redirects.

Try logging your variable and check how it works for requests to
index files, in a configuration like this:

log_format test "remote_addr:$remote_addr orig:$orig_remote_addr";
access_log /dev/stderr test;

set_real_ip_from 127.0.0.1/32;

location / {
index index.html;
# assuming index.html exists
}

You'll see it won't work with requests to "/", since an internal
redirect to "/index.html" happens and clears module contexts.
