Yes, half the number of blades would require about twice the angle of attack on remaining blades to maintain same overall tail rotor thrust.

I wonder if both blades departed at 'same' time or whether the massive vibration of imbalance after one parting caused the opposite one to then also fail shortly afterwards due to overload?

Lucky for it to end so well.
