What is the meaning just by design?

I don't understand.. I wonder why result came out differently in python and Bi either? And why the logic is necessary? How can I erase this restriction?

you need to add a column that prevents the deduplication from being effective

That is by design.  It is only a note to you, it is not an issue.  (Well, unless you see it like it is an issue for you. In whcih case you need to add a column that prevents the deduplication from being effective)
