You correctly replaced some buildings you previously mapped as round with square ones. The shape is more accurate but what you are looking at there is the skeleton/walls of a building under construction. Since it has no roof yet the internal walls may make it seem like multiple buildings but it should be mapped with a single footprint. again cross referencing (older) Bing may help as you migh spot some buildings which were under construction there and have been completed by the capture date of ESRI. Seeing some confirmed examples will help you better interpret the imagery.
