It's not a dumb question.

After June 2008 (and in some cases starting in May 08) the routing of the belts and belt type changed. Prior to June 08 the power steering used a clockwise rotation and the belts were single sided. After May 08 the power steering uses an anticlockwise rotation and a double sided belt.

Here is the routing for the "Pre June 08" setup.
Here is the new routing "Post June 08" setup.

I updated my OP (good question): May appears to be the cutoff point for some so if you have a May build you might have either best to check first.
