Hi Finns,
Yes it’s in this specific order to allow the PTU self test. Pay attention next time you switch off both engines you will see the PTU memo on the lower ecam.
EDIT: Can’t find the info in the FCOM to back up what I said above... I might be wrong but I’m sure it’s something to do with the PTU...
