Answer 1

It is because (Oracle doc reference)

COMMA_TO_TABLE Procedures

These procedures converts a comma-delimited list of names into a PL/SQL table of names. The second version supports fully-qualified attribute names.

A "name" referred to here is a valid Oracle (DB object) identifier, for which all naming rules apply. ac_Abc.88 is not a valid name, because in Oracle you can't have an identifier starting with a digit.
