The second argument to tokenize() is a regular expression, so , * means
comma followed by zero or more spaces.

I would write it as ,\s*, which is clearer and handles all white space
(space, tab, etc.).

Which in my case makes sense option A or B or C (A,B,C) which is simple?

So ",*" is acting as comma followed by wildcard?
(not even regex is it?)

Being v.suspicious of David and his mathematical mind, it wouldn't surprise
me if he has other aspects in mind :-)
