No reports filed as far as I know Sqwak 7700.
This was just a requirement that all controllers had to comply with. As 99% of helicopter operations at CLK are the GFS, it was simply arranged between CAD and the GFS that this was what was going to happen. Very poor 'Threat & Error Management'.
A controller, who had a friend who was a a senior lawyer, ran this CAD requirement past him and was advised that CAD and the controller would not have a leg to stand on if there was ever an accident.
As I said, CAD were pressured by Cathay Management and didn't have the guts to say NO to them.
No need to report sighting a helicopter unless you are basing your flight path on that of the helicopter, which should never happen. They are a VFR operation that base their flight path on what you are doing. Also, ATC are relying on a standard called 'Reduced Separation Minima in the Vicinity of an Airport' which requires the controller to see both aircraft involved.
