Everything about the rules is exactly the same, except that between two or more players who beat the game on both loops, your relative High Score between other double-loopers becomes irrelevant, and the tiebreaking condition is Number of Lives Remaining.
The reasoning for this rule is that within the top tier of players, the winner is not the one who took the most time and was most careful, but rather the player who was able to get hit less.
This rule presupposes that if you beat the game on both loops, you will have a higher score than someone else who doesn't. (I know in Contra killing the last boss is worth tons of points so I'm assuming its similar here) Which is to say, if you double-loop you are already in the top range of the leaderboards based on Score.
Since Lives are based on Score, there would still be a no-pressing rule, but at the top level of competition, it would feel more like a neck-and-neck, meaningful competition rather than a "cheap victory" (ie, "you killed two more enemies than I did")
My $0.02
Maybe multiply your final score by your number of lives remaining when you complete two loops.
