The condition you're referring to only occurs on one specific type of shuffler, called a CSM (continuous shuffler machine). These are the kind where the dealer feeds previously discarded cards back into the machine every hand or two, and there is never any pause in the game. CSM's are less common than traditional shuffler machines, where two decks/shoes are used, and one is being shuffled while the other is being played with.
