There’s a difference, signing the book is done before you vote in person in ny, and is not associated with your ballot or who you voted for. So in person there’s no way to know who you voted for.
For mail-in, you don’t sign the ballot itself. You sign the envelope, which is used to validate / track who voted, but is then separated from the actual ballot before counting so there’s no way to track who you voted for.
