Not true, QF has codeshares on TN but no FF participation. BA used to have codeshares with HA but I don't think there are any presently (not sure). There are lots of airline relationships outside of alliances, or even across alliances, and some of these are persistent. For example SA and QF codeshare between South Africa and Australia and this was renewed after SA joined Star (for good reasons). Hard to read too much into these agreements, at least in terms of future alliance membership.
