That's a total credit for 2 runs produced for every run that is actually scored, EXCEPT when the run scores as a result of a home run.
Adding up RBI and runs scored is a fine indicator of runs produced. Subtracting home runs doesn't give you a better idea of a player's production. All it does is add an element of complexity to a formula that is more accurate when it's kept simple.
It doesn't penalize the player. It just prevents counting the same run twice.
When you start combining counting statistics, you have to account for duplication like that.
You want to talk about runs knocked in, sure, you count the HR as an RBI.
You want to talk about runs scored, same thing.
When you want to talk about the runs that Player A contributed to his team in a given period compared to the runs that Player B contributed, though... Player A's home runs still only accounted for one run. Giving him credit for them in R and RBI (without subtracting the HR count from the total) makes it look like Player A contributed (number equal to home runs) more runs than he actually did.
