Absolutely true on astronomical scales.
An unnecessary complication if you're dropping a brick out of a window.

It's funny how much of physics we do assuming a flat earth.
If you did it "properly" you would calculate the orbit of the brick (assuming earth was a point mass), then find the intersection between that orbit and earth's surface. But for small speeds and distances you can just assume g points down as it would in a flat earth
To do it properly you have to account for the gravitational pull of the building.
