The breaststroke finish position is just like every other stroke,...

Pay attention the elbows, not the hands.
While the hands are obviously out in front rather than down by the hips, the elbows are very similar.
Pulling the arm to the side with the pecs and the lats allows swimmers to deliver a lot of force to the water.
If the elbows end up behind the torso, they’re overdoing the pull, and setting themselves up for a difficult recovery.
Understanding the nuances that apply to breaststroke can help your breaststrokers pull better and swim faster.

While 'deliver a lot of force effectively' is in many ways the bottom line, lots of nuance discovered here.
