That is actually one of the things where the airbus non-moving thrust levers have a slight advantage: if the lever seizes or jams, one still has autothrust available on that engine up to that thrust lever angle (if it is below the CLB detent). I have no idea how Dassault plans to implement its system, but that may be a way of working around that particular issue.
It will be interesting to see how they will implement that system and how it works in its final version.
