[opensuse] zypper ps, a bug or?

After entering "sudo zypper dup" I am asked for the root password before anything goes. When I use "sudo zypper ps" in order to see eventuell dead commands I have to supply my password again. So far as expected. But when I enter "sudo zypper dup" right after running "sudo zypper ps" I am not required to enter my password.
