and the ATC transmissions on the video posted above are (time) edited and partial.
Those recording are mostly made by spotters small scanners that only work line of sight and will often miss transmissions., as was last demonstrated for instance in the recent Kathmandu Dash 8 accident as we had here dozen of pages debating a scenario based of the partial R/T which had little to do with the real situation if you had access to the full recording.....
Drawing conclusions on those partial communications is futile.
