The tool jams against the chain on the sprocket and the timing cover to prevent it from falling down or jumping a tooth. Using the wedge is probably the safest method. Although some members on here have used a folded garden hose to wedge. You might be able to download the instructions for using the wedge and get a better feel for what's going on. If the chains gets off a tooth or falls off the crank sprocket, you'll have to take off the timing cover and lot more stuff to get it back to the correct position.
