FWIW, it seems that the same issue is present with tar:

$ touch foo.exe
$ mkdir -v foo
mkdir: created directory 'foo'
$ ls -l
total 0
drwxr-x---+ 1 knellis Domain Users 0 Sep  9 09:46 foo
-rw-r-----  1 knellis Domain Users 0 Sep  9 09:46 foo.exe
$ tar cvf bar.tar foo
foo/
$ rmdir -v foo
rmdir: removing directory, 'foo'
$ tar rvf bar.tar foo
foo
$ rm -v foo
removed 'foo'
$ ls -l
total 12
-rw-r----- 1 knellis Domain Users 10240 Sep  9 09:47 bar.tar
$ tar tf bar.tar
foo/
foo
$ tar xvf bar.tar
foo/
foo
$ ls -l
total 12
-rw-r----- 1 knellis Domain Users 10240 Sep  9 09:47 bar.tar
-rw-r----- 1 knellis Domain Users     0 Sep  9 09:46 foo
$

So, tar indicates that it extracted both directory foo/ and file 
foo, but the result indicates that the file won the conflict.

If tar actually did extract the directory first, I'd think that 
it's next attempt to extract the file with the same name would 
fail, but that's not what happened.
