Forget about the sex. Look at the relationships. A vee has one person who is involved romantically with two people who are not involved with each other romantically. A triad has three people, each of whom is involved romantically with the other two.
Having a threesome is no indicator as to the relationships. If the two Ms are not romantically involved with each other, there's no triad structure, just a vee that indulges in sexual threesomes.
When speaking of various forms of non-monogamy...it ain't poly if you're just fucking around.
While polyamory, open relationships, and swinging are all distinctly different approaches to non-monogamy, they are not mutually exlusive. Folks can, and some do, engage in more than one of them at a time--and it's all good.
