Possible error in 'test_die' unit test case?

In the downloaded unit test file 'test_dice.py' there is a test case 'test_die' which creates a default instance of the class 'Die' without any arguments:

class DiceTests(unittest.TestCase):
    def test_die(self):
        die = dice.Die()
        self.assertIn(int(die), range(1, 2))

When no arguments are passed, the 'Die' class defaults to 2 sides (basically a coin) with a random value within the range of sides, so in this case a random value of 1 or 2:

class Die:
    def __init__(self, sides=2, value=0):
        if value > sides:
            sides = value
        if not sides >= 2:
            raise ValueError("Must have at least 2 sides")
        if not isinstance(sides, int):
            raise ValueError("Sides must be a whole number")
        if not value in range(0, sides + 1):
            raise ValueError(f'Roll value must be between 1 and {sides}')
        self.sides = sides
        self.value = value or random.randint(1, sides)

Given the possible values of 1 or 2 for a default instance of 'Die', shouldn't the line

self.assertIn(int(die), range(1, 2))

in the 'test_die' case above be

self.assertIn(int(die), range(1, 3))

in order for the stop value of the range to include 2?
