I think Bivol is not hurt by the power of Beterbiev as they could have trained or have sparring partners that are really heavy punchers. So there are a lot of variables that might be in the rematch and as majority says, it could be another close fight and the judges will have to score. One thing though with Beterbiev is that he is patience enough in this fight. Another adjustment and this is just my personal opinion, Bivol should trade more in the rematch so put a good impression on the judge.
However, we can compare. But not 100% similar to real life boxing. The argument is for Bivol to create an adjustment in his tactics and in his training. Is this not considered a good strategy if a boxer has lost against the same opponent? I very much will reply yes for this question.
If there will be no adjustment from Bivol, we can be quite certain that this will be a similar fight with a victory that might be again given to Beterbiev.
