CentOS does not have a server register mechanism that pushes updates and all updates are pull to the client. CentOS uses either yum or up2date (run on the client) to pull updates from our mirrors (or from a local mirror if you configure it that way). Most users use up2date on RHEL (which is pull as well), so this is not really a major issue, however centrally controlled push updates is another benefit of an RHEL subscription.
