A good grader operator would know how to rotate the blade 180°from normal as if he were going to grade while driving in reverse. Most graders can lay the blade down quite a bit Almost to horizontal. If you watch the vid in stop action the blade is not spun 180° so he is not using the cutting edge. But there is almost a brief glimpse of something that could be an attachment to the top of the blade with a cutting edge It is nearly impossible to see, and I could be mistaken about it even being there.
But logic would dictate there would have be some attachment with a cutting edge to get under the pavement.
