I see what you are saying with how it would work for a flat ceiling.
Google says:

I have vaulted ceilings that prevent this 'updraft; from occurring.

Your google quote is what I was saying is the correct method and intended use.

Also, it shouldnt matter the shape of the celing...its still going to circulate correctly. You might even save some money if you reverse the direction...your A/C may not have to work as hard.
