Currently G+ has a bug in the chat when used in multi-account scenario. I hit it since the first days and reported it but obviously it's still not resolved. I didn't research it in details but I think that the chat loads always with the last logged-in user even if your G+ shows another profile. Also if you send messages to others they will see them as from this user. That was actually how I discovered it - a friend of mine told me that I'm sending the messages from my other Gmail account (which I don't use as a primary in G+).
Weird, the G+ chat just showed me IM's from my wife's Google account... there might be a privacy issue on multiple-user machines?
