I would imagine the last official entry was in 1940 and that Ali or the vet association added the reat at a later date.
My Livret was signed off on when I left the army, since then i have had some awards that were given out retroactively. If I wanted to enter them then we would have the same situation. I would enter them and it would arouse questions when it is a collectors hands 40 years from now.
Dont forget, the Croix de combattant is a long after the fact medal, some awarded 10 or 20 years after someone leaves the army.
Although the association medals are not official, many old soldiers dont realise that, and I as Ali was a civvie all those years later, there was probably noone to stop him entering the "croix de combattant European". I have seen a number of soldiers, starting with WW2 German vets and ending with Afghanistan Vets who have this and think it is legitimate.
Once someone is out of uniform whats "official" and not come become blurred, and in some cases uninteresting to the wearer.
