Nobody calls the rotor a 'vertical propeller' and translating tendency is a term of US origin, it is better understood when called tail rotor drift, with tail rotor roll the description of the fuselage attitude after the rotor had been tilted to counter the drift.
If your springy-thingy is wound too tightly to accept my characterization, then you are part of the reason beginners have a tough time understanding helicopter rotors, their design features, how they work, the job they do, and the side-affects of it. A Tail Rotor IS in fact a vertical propeller that produces horizontal thrust, and a Main Rotor IS in fact a horizontal propeller that produces vertical thrust.
If a beginning student's first exposure to rotor systems is through this viewpoint, and as their depth of understanding grows, they continue to process ideas through this idea, they will fully grasp all the other complex principles like flap/hunt/feather, transverse flow, driven/driving/stalled regions, dissymmetry of lift, retreating blade stall, and all the other tough to grasp subjects.
