Override instructions in README.md seem incorrect

Problem/Motivation

Behavior seems inconsistent with the instructions in README.md on overriding configuration in settings.php. With the settings below I would expect Drupal not to display a message on screen, and to insert a notice into the body of rerouted emails, but the opposite seems to be happening for me:

// Force enable/disable displaying a Drupal status message when the mail is
// being rerouted.
$config['reroute_email.settings']['description'] = FALSE;

// Force enable/disable inserting a message into the email body when the mail
// is being rerouted.
$config['reroute_email.settings']['message'] = TRUE;

Proposed resolution

I think the simplest fix would be to edit README.md as follows:

// Force enable/disable displaying a Drupal status message when the mail is
// being rerouted.
$config['reroute_email.settings']['message'] = FALSE;

// Force enable/disable inserting a message into the email body when the mail
// is being rerouted.
$config['reroute_email.settings']['description'] = TRUE;
