edit: The reason I find it an odd term is because human ancestry literally doesn’t follow a line. It always branches off, even if only to just include two parents. It’s a tree like structure, a line would misrepresent it

Imagine a line running only down the tree connecting two individuals - that’s a bloodline
If you can draw a bloodline from one person to the other, they are of the first’s bloodline. Your full blood siblings are not in your bloodline, though you share all of each other’s bloodlines
