Domes are great in one direction, because any given section has something below it. They’re a 3D arch, something whoch would fall apart immediately if turned upside down. The great part about big rounded edges is that they distribute pressure more evenly and reduce the amount of seams present unlike a welded cube, for example.
More likely is that, yes, the connection between the roof and the rest was the weaker point and also the dome was able to basically be a parachute so it coukd catch air instead of just being flung in some random direction.

An arch or dome made of stone would instantly fall apart if flipped upside down. A steel one will perform just as well, as steel is isotropic.
