I don't get it: does read use fd 0 as standard or is 4 a pre-existing fd? Is read v <&4; the same as read v 0<&4;?

@LePloit - ...uhh. both. I put the read command in a {compound command} context, and so all redirections which occur to the right of its closing brace are applied to the entire group, and they are applied before any enclosed commands are run. So &4 pre-exists the read simple command.
