Safetypee,
sorry, I would not know any of what you ask me, I merely responded to your query about the Swiss German expression.
The impression I got from the report about this sequence is that they were in a checklist and the FO queried the item from the checklist and got the reply "Do it". If it was not a checklist item, then the FO had some reason to query it at this particular time, and got the answer in the affirmative.
All I can contribute to this.
Best regards
