Hmm, du -ls is for duplicate traversal on hardlinks.
Without -l (default: opt_count_all=0) it should IMHO be fixed to ignore 
the second /usr/bin

$ ls -id /bin /usr/bin
2533274790648232 /bin  2533274790648232 /usr/bin

Same inode, so it's easy to check.

mkdir -p /tmp/test/test1 /tmp/test/test2
cd /tmp/test
# junction or mount is the same here
junction `cygpath -w /tmp/test/test1` test3
cp ../* test1/
ls -i
   22236523160786906 test1   9288674232096745 test2  22236523160786906 test3
# test2 is empty, test3 hardlinked to test1
$ du
2636    ./test1
0       ./test2
2636    ./test3
5272    .
$ du -l
2636    ./test1
0       ./test2
2636    ./test3
5272    .

=> coreutils bug with du opt_count_all=0 ?
