The vast majority of footprints are accurate here, but the round ones are not appropriately shaped. Generally these footprtins are inaccurate becasue you have included the building's shadow in its footprint. Accurate footpritns lead to better population estimates and prevent data overlap issues. Building footprints can generally be mapped slightly smaller than the roofs you see in imagery.
