It looks to me like it's just talking about HTTP the protocol, as in GET, POST, etc., and saying that you can reuse a SPDY session instead of opening a new connection — it's not saying you can use SPDY over unencrypted HTTP.
As I said, SPDY always runs over TLS. What we're debating here is whether you can request an http: URL over a (secure) SPDY connection. I see no reason why not and it should be faster, yet it appears that this isn't being done.
