Actually, no it isn't.

The demo is properly due on the 14th, with multiplayer becoming active on the 17th. The BF3 early access lets people play multiplayer on the 14th, this early access lets people download and play the single player portion of the demo immediately, as in right now. Multiplayer will stay locked until the 17th unless the player has the BF3 early access.
