The way it sounds here is that only one of those ten can access your library at all at one time. So if you have 20 games shared, and somebody is on there playing Peggle 2, then everybody else (the rest of the "family" group, not yourself) is presumably locked out from the other 19 games.
Having read, It does sound like that yes. But I don't get it. If I make a 'family' with friends, what's to stop one the fuckers playing a game and locking me out of my console until they finish. Doesn't make sense. Equally, allowing anyone of 10 people to play any one of my library except the game I'm playing doesn't make a lot of sense either.
Either I'm fucking dumb (not beyond the realms of possibility) or this still isn't clear....
Edit: I am dumb because I didn't read the bit of your post where it says 'Everyone except you'.
