Looks like it's asking me to replicate live and neutral, connect SL to A2 and split live into A1 as well.
That's how I'd read it, to be explicit I'd expect you should do the live into L and then have a short section of the same colour wire (black brown if you're using the existing wires) to jumper L to A1.
