My French was never good enough, but Google's translation is:
from La Figaro:
The research will once again take place in a circle of 40 nautical miles (72 kilometers) around the last known position of the flight AF447. The goal is to finish browsing north of the area that was observed last spring and then systematically sweep the entire area back down south and the last known position of the aircraft. Many experts believe that because the wreck lies further south.
I can see that this might be interpreted various ways, but I would interpret it to mean that the area east and north of the last search area will be covered, that LKP is included in the search area, and also a large portion of the southern area. I am thinking that "sweep the entire area back down south" refers to the area of the 40nm circle, and not to the area searched in phase 3.
