That there's a link between being single and promiscuous isn't as readily assumed in the overall culture as a link between being poly- and promiscuous. That's one aspect.
When we tell someone we're poly-, not a lot of people are going to think "Oh, I'm hearing this because I've made some recent assumption that's being corrected" or "Oh, this person has decided to talk more candidly about what's real in their life". The reason that a lot of people don't think that is just because they probably have no idea what it's like to have to choose between coming out and lying by omission. So the first reason they can come up with for coming out is "This person wants to tell me that they're available."
It's goofy, but I think that's also part of it.
