exception quando passa o .hasNextLine() para uma referencia

Boa noite rapaziada! Fiz o seguinte código, que está lançando a NoSuchElementException

package br.alura.java.io.test;

import java.io.File;
import java.util.Scanner;

public class TesteLeituraTwo {
    public static void main(String[] args) throws Throwable {
        Scanner scan = new Scanner(new File("contas.csv"));
        boolean tem = scan.hasNextLine();

        while (tem) {
            System.out.println(scan.nextLine());
        }

        scan.close();
    }
}

console:

Exception in thread "main" java.util.NoSuchElementException: No line found
    at java.base/java.util.Scanner.nextLine(Scanner.java:1651)
    at br.alura.java.io.test.TesteLeituraTwo.main(TesteLeituraTwo.java:12)

porém, ao se utilizar o scan.hasNextLine() diretamente no while, roda sem problemas:

package br.alura.java.io.test;

import java.io.File;
import java.util.Scanner;

public class TesteLeituraTwo {
    public static void main(String[] args) throws Throwable {
        Scanner scan = new Scanner(new File("contas.csv"));
        boolean tem = scan.hasNextLine();

        while (scan.hasNextLine()) {
            System.out.println(scan.nextLine());
        }

        scan.close();
    }
}
