I just confirmed that this is what happens.

method:

$ mkdir test1
$ cd test1
$ echo "a;ljfasldja;ldkfja;sldkfjsd;lfka;;slk" > file1
$ cd ..
$ du
4     ./test1
20    .
$ cp -rl test1 test2
$ du
4     ./test1
0     ./test2
20    .
$ rm -rf ./test1
$ cd test2
$ ls -l
total 4
-rw-r--r-- 1 david users 33 Jul 16 15:17 file1
$ cd ..
$ du

4	./test2
20	.
