Nope. I understand the differences perfectly.
As rod length increases, side loads decrease. Efficiency improves, cylinder and piston wear decrease. Of course, it does make your engine block taller/heavier and it does increase reciprocating mass. You can get some of that mass back with a less robust piston.
As stroke length increase, side loads increase. This is a bad thing, but, it is the cost of getting greater torque and efficiency gains of a longer stroke.
The concept is a lot simpler to understand with a picture. I'll see if I can dig one up. It certainly made it a lot clearer to me.
