Sorting friends by recent activity: what is "active"?

Topic

I'm wondering what the system considers "active". For instance:

PT13 shows in my friend list as (11 months ago) while on their profile feed the last activity is July 19, 2012.
Rubunny shows in my friend list as (9 months ago) while on their profile feed the last activity is August 28, 2012.

I think it means the last time that they logged into the game.
