That is correct. When you link to a source-citation, you only have one copy attached to multiple facts. If you change anything in the source-citation, that change appears for all facts because there is only one copy. When you create a new copy, (paste duplicate), you are adding an additional copy. Each of which are separate and distinct from the other. I have made use of this feature. I may find two families on the same page of a census. I enter the source-citation for the census page including lines for the family. When I begin sourcing the second family, I Paste a duplicate copy or the source-citation. I make changes in the lines. I then copy the changed source-citation and link it to the family members. Consequently, I have two distinct source-citation, each of which are linked to their own set of family members.
