Correct; swinging is just as valid of a "lifestyle choice" as polyamory, but it does carry with it the stipulation that it is all about recreational sex outside of "the relationship" for the purpose of augmenting the sex-lives of the people in "the relationship".
I don't want to hijack the thread; I wanted to emphasize that I don't think there's anything wrong with swinging, however it is not synonymous with polyamory just because both may involve sex with more than one person. In fact, polyamorous relationships don't even have to involve sex at all.
