The exclude mechanism does not mean "do not ever look at this file". It
means "when you are adding untracked files, do not include this one".
Somebody has already added the file to the repository before your
exclude was in place, so it is a tracked file.

There is currently no official mechanism in git to do what you want
(there are some hacks, but they include many pitfalls).
