As a European-trained Controller I watch that video and R/T with some bemused feelings. Instructing one a/c "maintain visual " and let 2 heavies get so close on radar without saying something is remarkable.
In this scenario only the Cathay could maintain visual since he was behind the United all the time. I guess this situation is a daily thing for the SFO controllers and working well 99% of the time , and basically this is what you get when you want to move the traffic they do in parallel runways.
I flew a couple of times into Oshkosh ( again a few weeks ago) and the approach there not what you will call "European" but it works., and works very well even . Respect..But to get there you need to read a 30 pages instruction booklet beforehand.
I am not so sure the foreign airlines crews operating in say SFO , have all read and understood the booklet ( if there is one) on the local procedures and the differences between US ATC and their home turf.
