How to understand the 'Works perfectly with'?

Hello there,

If a pluging is 'checked' for 'Works perfectly with'; WordPress 3.3.1, WordPress Multisite 3.3.1 and BuddyPress 1.5.2 - can I then expect it to work ONLY with all this (MU/BuddyPress) on my site? Or can I expect this to also work on a plain WP installation?
