Looking at damage overflow again, consider a simple case where one character gets one 20 damage attack, and another character gets two 8 damage attacks. DPR is clearly higher for the first character, but the second character has significantly better odds of dropping anyone with 0-8 HP, and low but not nonexistent odds of dropping two targets with 0-8 HP in one round.
The L5R comparison is more like one character getting one 20 damage attack, and one character getting one 16 damage attack. There's no additional options there, just a worse version of the same option.
