Yeah. I'm not sure. I'm leaning about 85% that he embellished and faked it, but I see the rationale that perhaps he did get clipped and the video isn't providing an accurate measure of what happened. I don't know though and as of now, I'll stick with my assumption that he embellished.
Take a look at the image posted by acoustic. Sure its not 100% clear, but it does seem to show the stick right in Marleau's face...
