In choosing between repeating a field and repeating subfield $a: If the vocabulary source differs or if some terms come from a controlled vocabulary and others are uncontrolled, repeat the field. Otherwise, if the only addition to an existing field is an additional term from the same vocabulary, either repeat subfield $a or repeat the field. Overall best practice: repeat the field when needed for clarity.
