All Up or Parlay bets that include a scratching remain "live". The system
treats the bet on the scratching as a money-back dividend that is reinvested on the next leg.
If all selections in all legs are scratched, the bet is fully refunded.
If a race included in the All Up or Parlay bet is run out of order, All Up betting is abandoned on that leg, and the bet and any reinvestment is moved to the next leg. Dividends can be paid after all legs have been run and processed (including the race run out of order).
