So all these words to complain there are two head set set-screws in stead of one?

Only things I can think of is there is no real retention of the two set screws. > Use loctite, or the collar fixating the FS cartridge doesnt stay in place, but I have heard no such thing.

Re. #1 "What is the pitfall with having two bi-lateral screws control FS retention? Competing inequivalent torque can cause cocking of the Future Shock inhibiting shock stroking." What are you even trying to say? How would the two head set set-screws prevent the FS cartrige from working?

Re. #2 Equally convoluted language. You seem to not understand the set screw on a standard head set, does noting once the stem clamp is tightened. You can take it out if you wish. If the set screws/pre load is set right, there is no "stroking shock" to either a normal or FS headset assembly.

Overall I do agree its a little bit fiddly, but that, IMO, is to be expected with a suspended design.

Im not sure what Im supposed to see in the video. Anyone can struggle with anything. Lots of ppl doesn't know how to put on on a new chain or patch a tube either. Doesn't mean tubes or chains are rubbish
