There was no agreed standard for wall lights. For the ceiling rose there is a convention of supplying each rose in daisy chain manor then running the switch wires to and from each ceiling rose.
But wall lights don't use ceiling rose so it is up the the electrician to find a suitable method.
If you only have a single cable at the wall light then likely all joining has been done at the switch and all you need to do is re-route the cable adding any cable as required using proper joint boxes designed if required for zero maintenance (i.e. no screws push fit for cable with clamp) or one of the other methods allowed when cables are not accessible for maintenance.
