Good point. Clearly with sudo, aside from it following the UNIX convention for sudo, it is just a consciously made tradeoff between security and ease of use. Whereas with the security pane, the lack of checking of the password that is entered is most likely a bug. Maybe you already saw this but I see they also made the same security/ease of use tradeoff for the (non-buggy) locks in the other preference panes. After unlocking, it stays unlocked for a period of time while you are in preferences, even if you visit different areas within preferences and come back.
