Ball placement, free kick OOB - FED

[stripes1977]

Is there anywhere in the rulebook, casebook, etc...that specifically describes something like this? Or at least a way to derive the answer? I can see the argument that it would be placed on the same hash from where it was snapped since that IS the last place from where it was snapped, and I can also see the logic in snapping from the side it went out of bounds. Guess I just like to have some concrete to stand on when I explain this to others, that's why I like to know where in the book it is.
