The problem isn't that code reviews get recognized and rewarded, it's that once a change is merged you can't review it, so people "race" to review changes before their colleagues get to it. That's not a healthy system. It's better to let people manage their time to promote flow, letting them batch up code reviews at a certain time of day if that's more effective. I'll just add that nowhere I've worked has counted code reviews in this way and they still get done, so it's not a disaster when you don't officially penalize people for their review count.
