That's completely safe. As climber's say, the gear is bombproof. He is tied to a rope which he anchors at regular intervals, so the furthest he could fall would be a few metres - not that any averagely competent climber is going to fall off that.
around 25ft is generally considerd as 'splat height', so you can go as far above that as you like and it makes no difference.
It's little wonder your confused when you think you hear stories about '70's racism Mammutly, after the post above you obviously view/hear whatever you personally want to.
What that Vid did'nt accurately highlight was the wind and it's effects. I did some work on the tower over in Louth in the '80's (at the time the tallest steel structure in europe) and the observation room was set up so that the Klaxons were triggered when the room itself went 7ft out of centre (imagine the room your in having 14ft's worth of travel...only your at 1200ft). Getting down a 1200ft one man ladder (lively) with spanners hitting your swede keeps you fit/alert.
