How closely should twin names match?

Why do distinct initials matter for a twin of Penelope?
A lot of paperwork, from class lists to doctor's files, shows only a first initial and a surname. A twin of Penelope whose name also starts with "P" can be harder to distinguish from Penelope on some records, so the twin score rewards a different first letter. None of the names on this page start with "P".
