I have had private chats using G+ posts and I attest that they never turned public. Once you make a post, you can't change it's visibility. You can only delete it, or lock it down - comments or reshares.
Though I think gPlus + Wave would be the ideal such environment for me.
I once tried 'chatting' with my girlfriend on google+ using a private channel. The fear of some error happening, and our messages being accidentally shown to public was too much, and we switched back to chat. Google+ us social and public. Not technically. But that is what they are trying to be, and advertising to be.
