BuddyPress Activity Plus plugin

I see the "BuddyPress Activity Plus plugin"
Compatible with
WordPress 3.4.1
Multisite 3.4.1
BuddyPress 1.6

So even though it says BuddyPress Activity i am good to go without BuddyPress installed?

Also it says it will work with any BuddyPress theme!; if it does not need BuddyPress installed, will it work with non BuddyPress themes? Say twenty-eleven?
