Notice that the connecting rod on the cap has a 2D bar code on it. That bar code can contain lots of information that "MAY" be used to ensure the pistons, rods, crank and blocks are picked in a matched set........ Or........ it could just be a part number.
At a guess, if Mercedes was actually matching pistons with individual cylinders, they'd say so.

On the other hand, mentioning that sort of activity essentially declares that there are variations in the manufacturing/machining processes, which might make a casual viewer wonder about quality control.

That settles it. Swamp has to go visit the plant and bring back The Truth!
