Those are just examples of it done poorly, but its the same type of effect as the mansard roof. You make the top floor look like its part of the roof and it gives the appearance that the building isnt as tall as it actually is. It makes a 5 story building look like a 4 story building with a roof. Buildings need roofs, but you can make the roof another usable floor instead of just an attic. Its a design language that has carried on through generations.

It works a lot better on certain buildings/styles/colors/amount of floors than others. 1 top floor with a black facade and the effect actually works, especially if the floor is set back. A floor done in a weird color or trying to do it with 2 or 3 floors and then it just looks ridiculous.
