Arthur Borges,
It would seem from the BEA report that the AF459 crew was interviewed prior to its publication. There is an extensive narrative of the deviation flown by this flight, and their communication with Atlantico in that regard.

LH507 preceded AF447 at ORARO by 20 minutes (or about 0143). LH507 deviated west by 10 NM. (This may be the flight that was providing AMDAR reports. If not, the flight with AMDAR preceded LH507 by 10 minutes.)
IB6024 was at ORARO 12 minutes after AF447. IB6024 deviated to the east by 30 NM.
AF459 initially chose to deviate west by 20 NM, but then deviated to the east by 70-80 NM. AF459 was at ORARO 37 minutes after AF447.
AF447, instructed to contact Atlantico at INTOL, establishes contact with Atlantico at 0133-0135. How likely is it AF447 overheard LH507's deviation west? From the radio communication transcript, there is no indication that AF447 and Atlantico discussed the weather between ORARO and TASIL. Nor does the transcript contain (other than one or two references) the radio communications between other flights and Atlantico, say between 0100 and 0300.
