You know, I was watching that video expecting to see an antenna still standing while the roof was ripped off.
I read about the glue up PITA issue you talked about and was fretting it too. The version I received did not require glue. The couplers simply slide over the lower section and are tightened in place with an allen wrench. Nice!
That is a very nice antenna. I installed one on the roof of my house about seven years ago on a 20' mast secured by a heavy duty tripod. I went a bit overboard by using 7/8" Andrews heliax. It's been a rock-solid performer and has survived many gusts in excess of 60mph, and a derecho last year with highest steady winds of ~90mph! See: https://twitter.com/...938287296974856 showing an apartment building being "de-roofed."
Those masts are great, although measuring and marking each section and gluing the toggle clamps was a PITA! I have two of them and use the tall tripods from MFJ along with two levels of guy lines to support my G5RV (106' HF antenna) on field days and other club events such as POTA (Parks on the Air) activations.
