I have a dumb question, thanks for the help in advance

Strickly speaking "Hi/Lo split" designates the game as the best high and best low, with out regard to any qualifiers.

"Hi/Lo 8b" or "8b" designates that for a low your hand must qualify by having a five card poker hand with 5 cards (not paired) [8] to [A] for a low. If no one has a qualifying hand for low, the high hand(s) scoops the pot.

Most card rooms treat them as the same game, but it is better to ask before you get involded in a pot when you enter a game. This is to make sure you know the local rules.
