My guess is that the tail wheel comes down for the same reason. I doubt that the there is much of a problem with being tail heavy unless they park up with fuel left in the tail trim tank. That's unlikely since fuel is pumped to the forward trim tank during the descent. My Concorde book also says that the fuel has 3 uses (balance, cooling and propulsion). Most planes only have one use for the fuel although the SR71 also uses it for cooling.
