This is meant to be a clarification, once again. There could be a problematic situation where the parliamentary budget officer would hold more than one office.
I could read it in English:
The Parliamentary Budget Officer shall perform the duties of the office on a full-time basis and shall not hold any other office or engage in any other employment for reward.
I think that this amendment is straightforward. It specifies that this is a full-time job and that it will not be tolerated that a parliamentary budget officer hold other offices.
I think that is reasonable. I can't see how anyone could object to that. And so, I hope that my colleagues will support me, so that we may include this measure in the bill and make it clear for everyone; while working full-time you cannot occupy more than one position.
