Behavior of realip module with this config

I've got the config below. I don't have these settings reconfigured
anywhere else. My understanding is that no matter anything else at all
anywhere else, and no matter whether the X-Forwarded-For field in the HTTP
header has one or multiple IP addresses, or isn't even present,
$remote_addr will not be altered.

real_ip_header X-Forwarded-For;
real_ip_recursive on;

>From what I read, "real_ip_recursive on" means that $remote_addr can only
be set to an IP address that is not in the range set by set_real_ip_from.
And since that's, there is no IP that can meet this requirement.

Am I correct in my analysis?
