I don't think it's necessary, but some people believe they are, or do it because it's the example they've learned from. I think if some people need labels, then labels based on "which one does what with you" are better than labels based on hierarchy.
So, instead of "Hi, this is my primary, Jack, and my secondary, Jill,"
one could say, "Hi, this is my money-honey, Jack, and my girlfriend, Jill."
