Tiles aren't positioned correctly on the Map

Hi, I'm facing an issue with the BBOX coordinate in Mercator. I have satellite images of the world and I want to add an MKTileOverlay to my map. The tiles are loaded correctly, but don't fit the according part of the map.

Indeed when I compare the values for a specific tile at an X, Y position for a Z zoom level with http://www.maptiler.org/google-maps-coordinates-tile-bounds-projection/

The minX, maxX, minY and maxY values are exactly the same. But the result is like a puzzle of the world organized in the wrong order.

Does MapKit and Google use the same projection and tiling profile of the world?
