Family Sharing and Online Co-op Multiplayer Question

[Brody]

Hello, I have a question.

If three people are using Family Sharing, and two of them own a game that supports online co-op multiplayer, can the third person (who doesn’t own the game) play online with one of the two who are sharing, as long as the other isn’t playing at the same time?

From my understanding, with a Steam Families group of 3 individuals and with a total of 2 copies of a particular game in a shared pool, any two members can simultaneously play the game. For the third person to join, one of the other two must exit.
