I think you missed the '?' quantifier after the quoted-string group. It is allowed to be absent, so the split will accept whitespace alone. It also eats trailing whitespace after a quoted section.

The captured string between the quotes is the only element of the regex that is passed into the list result of split. If there is no quoted string, that capture is present, but undef. Hence the grep filter.
