Updating Core WordPress

Hi All,
I have a client that has a WordPress site running version 3.6. I need to update to 3.8. The problem is that within the core files whoever set this up is not using the wp-content folder. Instead it is named management. They have this code in the wp-config file:
/** move the wp-content folder **/
define( ‘WP_CONTENT_DIR’, $_SERVER[‘DOCUMENT_ROOT’] . ‘/management’ );
define( ‘WP_CONTENT_URL’, ‘http://216.92.28.161/management’ );
/**
My question is, will this effect the update if I do via automatic update? Or should I do it manually? Also, why would you do it this way. Is it for security? Thanks in advance for the help.
