If it expires when the browsing session ends, why was it present on the 8/2/14 cookie list?

Cookies can contain anything a website wants to include, in any format or encoding it chooses, so in general it is not possible to discover the "meaning" of a cookie by looking at the data it contains unless you are privy to the scheme the website is using.

Likewise, it is not possible to tell whether a cookie is "third party" or not merely by looking at it: the exact same cookie can be "first party" or "third party" depending on the browsing context.

Expired cookies, including session cookies from a previous session, are not necessarily deleted from the browser's cookie store immediately upon expiration, but should not be sent in subsequent requests made to the website that issued them.
