I am not sure who that particular pilot was in the video. I know the lineman, he was my guinea pig for my initial external work platform training. Great guy. I have only been with this company for a few years, but there are a few ridiculously high time pilots (and lineman) here who have been doing this for decades. They have my utmost respect.
As to the winds; it depends. There's no defined number to stop operations. It's just a matter of aircraft control, position, and configuration. Wind (and aircraft weight) are always the most limiting factor when performing platform operations.
