Vertical separation [Air Traffic Control]
Between the surface and an altitude of 29,000 feet (8,800 m), no aircraft should come closer vertically than 300 metres, unless some form of horizontal separation is provided (Note: for countries that measure altitude in feet, a 1,000 foot minimum is observed rather than the 984.252 feet found in 300 meters). Above 29,000 feet (8,800 m), no aircraft shall come closer than 600 m (or 2,000 feet), except in airspace where Reduced Vertical Separation Minima (RVSM) can be applied.
Your picture is unclear in the 3rd dimension of altitude but I'd suggest, nothing to worry about. The Air Accident Investigation Board do also investigate Air Prox violations as well as actual crashes too.
