From what I could find, that pic should be of current progress on Hughes Reef / Dongmen Jiao? The existing structure looks like Johnson South Reef but the shape of the new island does not compared to previous pics.
I think that the first picture is a more recent close up of the top left hand corner of the full Island pic. The second island shows the forming of the new shape still submerged, while the top picture does preserve the original pointed cartography through relief.
