I don't disagree with what he says but he could have been done in a minute by stating the obvious: the up-and-down movement of your derriere is not driven by the frame material since it turns out double diamond frames are vertically stiff.
I'd recommend watching Jeff Jones demonstrate the purposely designed seatpost tube flex on his Spaceframe. https://youtu.be/rfGu3yGcnJQ?t=131 Hang out until 3:17 to watch him demo the truss fork's "lateral stiffness". I also like how the design of the Spaceframe and the GBW seem to rhyme as their shapes hint that their designers wanted the frames to flex in similar ways. --Ed C.
