If the striker has not played his shot prior to dropping the rest his opponent has the choice of playing the next shot himself (from where the balls finish up) or asking the striker to play again either from where the balls end up or from where they were prior to the foul. If the striker has played his shot before dropping the rest (as in the Mark Allan clip) the opponent has the option of playing the next shot from where the balls end up or asking his opponent to do likewise. There is no option in these circumstances to have the balls replaced. (Rule 10(i))
