or if you are being descended to a radar lowest safe whilst being recieving a surveilance service[ie I am monitoring you on a specific track ] then ATC must assign the min vectoring altitude and give heading or tracking instructions to intercept final or to position the aircraft within the circling area.
I think the question some are asking is why has the terminology (re visual approaches) in AIP changed from vectoring to ATC ss. It was changed when all references to 'radar' were changed to 'ss', but in this case it's not just a terminology change, it has changed the intent of the paragraph.
Prior to the change, the step down to MVA and papi's, ils RT was only required if you were vectored.
The change was only noted as an RT change at the time, not a procedure change. Anyone know?
