What difference does it make whether or not the RJ was rightly on or off the taxiway? Do you suppose the AF captain's argument of "I proceeded because I had the right-of-way" will carry much weight with his bosses when the repair bills come in?
No.
One need only review the nose camera footage of the Apache trying to squeeze in between the trees to be reminded that if you're not sure you can fit, it's likely a good idea to wait. Especially if you're driving the world's largest commercial passenger aircraft.
