the biggest reason is probably for the variance, but i think more often than not its just as a courtesy to the person who's behind so that he doesnt lose too much (especially in the high stakes games where the pot can b upwards of like 750k)...they know that the discarded cards are taken out of the equation, so they know the odds arent exactly 50/50 if they run it twice, depending on the outcome of course, but i think like someone else said earlier its generally just to be able to run it twice if you're ever behind urself
