Sometimes, sometimes not.
Remember when Valve's servers went down due to weather a year or two ago?
Some people it would work, some it wouldn't. Some file on your PC, not sure if it expires or what, but if you were not logged in to an account, for example, no go.
That said, I trust Valve a WHOLE LOT more than Microsoft or EA, so Valve is always my choice if I'm going to buy a game online.
