It's exactly the same Airbus tell about their plane:
Our aircraft and systems worked as expected ..
The aircraft had no fault.
Of course if you go out of the certification specifications ... you can have some weird outcomes ....
More like "if you go out of the certification specifications ... you can have no weird outcomes"

Safety critical systems are designed to perform well beyond the certification specifications (as we now know from the survival of DFDR/CVR). Even in extreme cases like partial shutdown/reboot of systems, I'd bet Airbus fully understands the behavior of the system.

To the extent that Airbus thinks the a/c systems did not misbehave probably means that there are not going to be any surprises in future BEA reports.

Having said that, my reaction to A33Zab's image of Ecam view was: Yuck
