If you watch the inter active video in the section where the guys who took the safer route down found ski gear sticking out of avalanche debris. The POV guys goes into his pack to pull out his beacon. When you are using a beacon, it should be used with the harness, attached to your body under your ski gear. Packs can get ripped off in an avalanche. Outer wear can get ripped, so putting it in a jacket or pant pocket is not recommended either. It's bad form, and not one avalanche school will tell you to do this.
At this point it's nit picking. I just don't know why you wouldn't wear your beacon in the normal fashion. You don't even know it's there.
