I didn't go into the details, because, well, that was more a side aspect of the blogpost. Technically you're right. However how you're setting these things depends on your needs. Let's assume you have a server where several people develop software on. You may want to allow them to create core dumps for debugging purposes. Whether you set a hard or soft limit thus depends on your use case. I'd say usually setting a soft limit is good enough. Yes, this means users can lift the limit, however if they play with the ulimit coredump setting I assume they know what a coredump is, thus it should be okay.
