As others have pointed out, this is not true unless the scoop is intentional (e.g., to illegally clear over an blocking opponent ball).It doesn't matter if it's a double hit or not, a "scoop jump" is always a foul, ergo ball in hand for you opponent.
For those interested, the video and surrounding discussion can be found on the illegal scoop jump shot resource page. Here's a direct link to the pertinent video:Dr. Dave's video's have shown you can scoop with and without a double hit
