Followed by a knee jerk reaction without any facts backing it up...

PS: Potted plants are often placed on the top of flat roofs with a lip and don't get tossed off it by the wind. The reason has to do with how the wind is deflected over the building and the obstructions around it. Often pushing them in opposite directions from the wind because of a giant counter rotating vortex of air. But, be happy with your inaccurate and over simplified model of how the world works.
