Well it would be security through obscurity if you changed the port, but didn't require any authentication on your ssh server. There was a time when people would do stuff like this, have a modem that would dial in to a corporate system without any authentication. With the idea being that they would have to guess the phone number. Then later on in the name of security making sure that you had to connect at a certain arbitrary bitrate. I understand the point of the article, I just think it's too narrow of a definition. The whole thing is just arguing semantics anyway.
