I am myself very wary of this kind of personality tests but the case has been made in an interesting article that I can't seem to find that it is a form of "syntactic sugar" for the (apparently?) more established Big Five model. Anyways, I think OP's conclusion that it is eye opening that people have their own emotional structure/pattern of behavior from how they grew up and that you can find resembling patterns in different people quite reasonable.
