I did. And it's not limited to csv file: all files in excel must have a
unique name, and the path is irrelevant.

It might be due to its long history... and the display of filename in
the window submenu. (it might be for the "benefit" of the end-users, so
as to not confuse them.)

Excel is a sandbox: it make nice graphics (yet not all of them keep
being available across its versions) but is usually overused for database.
It's fine to use excel as a sketch, but any real production should stay
away from it. Alas, it's so eye-candy that it usually stays with the
uneducated people in charge (like CEO and other administrative/marketing
people).
