That is correct. To get the fuse diagram, you will have to pay $35 for access to everything. Look on the bright side, take advantage of the situation, and download everything for future reference - it will come in handy.
VW stopped providing fuse diagrams with the 2012 Passat, probably because they don't want people dicking around in there hastily adding shoddy connections for whatever gizmos and gadgets they want to add. With all of the on-board electronics these days, it's pretty easy for someone who doesn't know what he's doing to screw the car up, requiring extensive troubleshooting and repairs. I don't necessarily agree with that approach - I'm just explaining it.
