The tail rotor is pushing the aircraft to the right, because it has a pure thrust. The aircraft does not lean to the left until the pilot sees the right drift and cancels it with some left bank.
The height of the rotor head has nothing to do with it, the height of the tail rotor relative to the head has nothing to do with it either. The height of the tail rotor relative to the cg of the aircraft (the vertical cg) is important, however. A high tail rotor cancels some of the needed left roll, a low tail rotor, on the centerline, needs more left roll.
Articulated, semi-rigid and rigid rotors all have the left roll tendency, the type of head has very little effect on the issue.
