Thank you.
The report says they are colloquially known as lead on/lead off lines. It is an everyday name given to the lines, it is not an instruction on how to use them!
This line is variously described colloquially as the ‘lead on’ or ‘lead off’ line depending on whether an aircraft is entering or vacating a runway
If you follow them to line up and you are performance limited then you have probably just invalidated your performance calculations. If you've done your performance from a more limiting intersection, then sure, use them as lead on lines.
