No, he's saying not to do it because a single rail PSU with over 1kW will not likely trigger OCP if a short circuit occurs. Basically, your house burns down - this is because 1kW+ on a single rail has a high OCP limit. Whereas multi-rail 1kW+ PSU will trigger OCP because each rail will have a lower OCP limit.
