Although I can see the sense in the decision, it is not as clear cut as it should be.

Origional in WH and Prov in rough = Play 4th with Prov as against PD with origional so playing 3.

Prov in WH and Origional in rough = Play 2nd with Origional.

Because it can not be certain which Ball is which, the Decision allows you to play your 4th shot from the rough instead of having to return to the Tee.

But if a 3rd or even 4th Ball is involved, the Decision does not really cover that. If a Player can't definately ID his Ball from two, what chance would he have with 3 or 4?
