I was on a boat the other day and one of the dealers allowed players to resplit 8's into 6 hands (I was on a 6D). He mentioned that the player can resplit as many times as he'd like. What kind of advantage does this give? The game was also available in 8D. Thanks!

Just in case it makes a difference, here are the other game rules:
DAS, NoRSA, Late Surrender, S17, DOA
