That's actually perfectly analogous to the behaviour of the unix cp
command, when copying directories:

---------- 8< -------------
bash-3.00$ mkdir test
bash-3.00$ ls -l
total 8
drwxr-xr-x 2 user group 4096 Dec 8 12:11 test
bash-3.00$ cp -r test target
bash-3.00$ ls -l
total 16
drwxr-xr-x 2 user group 4096 Dec 8 12:11 target
drwxr-xr-x 2 user group 4096 Dec 8 12:11 test
bash-3.00$ ls -l target
total 0
bash-3.00$ cp -r test target
bash-3.00$ ls -l
total 16
drwxr-xr-x 3 user group 4096 Dec 8 12:11 target
drwxr-xr-x 2 user group 4096 Dec 8 12:11 test
bash-3.00$ ls -l target
total 8
drwxr-xr-x 2 user group 4096 Dec 8 12:11 test

---------- 8< -------------

So svn's cp behaviour is simply based on the standard behaviour of cp.
