I must agree with Mike however, slapping the opposite shoulder is not a prerequisite as long as you execute the elbow with the same anatomical alignment. But I can see that slapping the opposite shoulder does aid in acheiving this alignment.
I'm going to agree with me too
I Can see that slapping your shoulder would have to put your hand in the right chambering position to execute a proper outward elbow, since it would follow a line rather than an arc if you had chambered somewhere else.
Also, by having your hand tight against your chest you have a strong brace for the outward elbow. If it is off of your body, then the arm is free to move.
If this is the final position of your elbow, then it will be strong.
