After a strong Finish, almost all professionals assume some variation of this balanced, rock-solid position. Most amateurs, on the other hand, finish in a teetering, off balance body position and soon have the club in only one hand (usually the right).
I strongly recommend that you practice swinging to the classic "Arrow through the Ears" Finish (see the Knudson video above at 0.05). Then, as you watch the ball streak toward fairway or flag, lower your arms into George's comfortable "Best Seat in the House".
