Thank you for reporting that.
It was a bug.
Here's the fix:

2005-01-05  Jim Meyering  <address@hidden>

        * Version 5.3.0.

        * src/du.c (process_file): Evaluate exclusion rules against
        the entire file name, not just the last component.
        Reported by Robert Lindgren.
        * tests/du/exclude: Test for this.
