Not necessarily. The guy must leave the girl's house before dawn, but that doesn't mean it's a one time thing without emotional connection. The relationship can be long-lasting, but they just don't live together.
As for how much "walking marriage" resembles polyamory, I've heard/read different things from different sources. According to some, Mosuo people are pretty close to poly, i.e. they can have multiple consensual relationships, and they don't even have "jealousy" in their vocabulary (I think that's from Sex at Dawn). According to others, they still mostly have serial monogamous relationships, despite a relatively open and free system.
