Is this going to loop until random returns a 0?

Yes we keep rewinding between >0% and 100% of the remaining blocks until there is nothing left to rewind.
currentHeight = random.Next(currentHeight - 1) + 1; will always reduce currentHeight.

Is this correct? This is different functionality to previously. This will pass blockHeight-1 to Rewind.

Yes. It's the target height. Previously we implicitly passed blockHeight-1 to Rewind. Now its explicit.
