Shit, one should really rewatch a video before linking to it. I was trying to get at the inability to move between -ve and +ve (total) curvature. Intuitively (ie guessing) a loading a domestic won't try to change the sign of the curvature, whereas loading a saddle will...?

I'll take your word for it. I always find it tricky to think of saddles.

You're not alone! On re-engaging of my brain, loading a dome tries to flatten it i.e. movin from +ve curvature to 0 curvature. But, I think it depends how you load your structures. Good knows. Ask a (academic) structural engineer!
