This is one thing that is troubling me as well.
This conclusion can reasonably be made by cross matching the timestamps of the ADB mode-s "selected altitude" messages with the timing of the sounds of someone pushing FMC buttons on the CVR.

Maybe true, but it is speculation.

In my opinion the French Prosecutor is not following ICAO Annex 13.
