I think the concept of an active context is whether or not you are in that context. For example, when I get home from work, I set my "home" context to active and my "office" context to inactive. Then if I filter on active contexts, I can see what I can do, and stuff I can't do right now stays hidden.

Edit: Hmm, guess I was doing it wrong. Michelle knows way more than me.

Edit 2: Adding something to test a bug in the forums.
