racketunit check is not throwing exception

(check < 4 3) is returning an error message on the screen but the function also returns #<void>. I was expecting it to return only an exception and not void. Do I understand the following racket doc incorrectly:

"If the condition holds the check evaluates to (void). If the condition doesn’t hold the check raises an instance of exn:test:check with information detailing the failure."

> (display (check < 4 3))
