If you uploaded this change-set seperately to 134399868, becuase you were unsure if these features are buildings, then very well done. It makes it easier for others viewing changes to the map and increases the likelihood that your change-set will be verified as good helping to identify high quality contributions. I believe that only the northern building footprint is valid in this scenario, the others may be constructions or perhaps small crop fields.
