Actuator has answered correctly as far as the yellow line is concerned.
In addition, to date, there hasn't been one single case of heavy MTOW (even pass the 1000K IBs mark) running off the other end due to poor line up technique. However, you can easily name quite a few incidents of big tubes scrubbing some mud/grass/taxi edge lights or even getting stuck during line up due to the every-inch-counts mentality (well at least that's how most of us were taught anyway).
The performance does allocate some sacrifices and conservatism, depending on a/c type. I personally will neither follow the yellow nor a 90deg, somewhere in between, with careful judgement of my wheel clearance being the priority is IMHO, the most practical way to line up.
