Consider your inexperience an asset in this context. The changes and the code should be (to some degree) self-explanatory. The star may crank out code like no other, but chances are they don't want to maintain it. So the review from your side can help to relinquish that responsibility. The point is though, there needs to be common understanding in that matter. (Also that it'll will take your time). It might make sense to talk about that with your colleagues and find an agreement.
