The reason it is calling the select() model "blocking" is because you block during the select(), not because the read() itself is blocking. This is also non-standard usage: most people wouldn't refer to a select()-based loop as blocking I/O, because a program generally only calls select() when it has nothing else to do but service I/O, so the select() does not "block" the application.
