From your link: "Before Apache 2.4.7, the DH parameter is always set to 1024 bits and is not user configurable. This has been fixed in mod_ssl 2.4.7 that Red Hat has backported into their RHEL 6 Apache 2.2 distribution with httpd-2.2.15-32.el6. Future versions of Apache will automatically select a better value for the DH parameter." So I suppose he does mean like that.
