@StephenM I'm not an expert so bear with me and if I get this incorrect, hopefully the others on this chain will correct me. The '0' is referring to an index or location in the string. Hopefully these links will help:
Optional. An integer that specifies the number of splits, items after the split limit will not be included in the array
