I can appreciate this philosophy but I don't think it's right for everyone. On the one hand, it's nice to have a safety net for times when pairing turns into one person programming while the other is spacing out. On the other hand, if you require a review on top of pairing then you're now requiring 3 people to get this chunk of code out. So there's definitely a balance and you have to decide what's right depending on your team and situation.
