This penalty shot thing happens all the time. For whatever reason there is a decent divide around the world on this rulling. It happened in Calgary a few years ago at their easter tournament. After much discussion over beers afterwards there were still some staunch belivers that no you can't go forward until the puck is touched. This lead me to an extended email discussion with Simon about the whole thing. It is explained a bit better in the level 2 refs manual.

I guess some are looking at the rules that don't say you CAN go forward and not allow it... I guess this should be clarified. It seems pretty straight forward to me,
before gong behind puck on surface.
after gong go nuts and go anywhere.
