in a stock motor, the pin is pressed into the rods and slips through the piston, letting the piston both rotate and slide into position, so a little off-center wont hurt it.
this is probably whats meant on the pistons you're looking at, as the its the pin thats pressed into the rod, and the pin comes with the pistons. a floating rod will need a floating piston, and the pin will be retained by spiro-locks instead of being pressed into anything.
