What is the purpose of these test methods?

What is the purpose of these test methods in auth.go?

h.ab.Events.Before(authboss.EventAuth, func(w http.ResponseWriter, r *http.Request, handled bool) (bool, error) {
  w.WriteHeader(http.StatusTeapot)
  beforeCalled = true
  return true, nil
})

It writes a status teapot before the auth event, and then checks to see if that status changes:

if resp.Code != http.StatusTeapot {
  t.Error("should have left the response alone once teapot was sent")
}

Why would the status not change? Why is this being tested? I can see that this verifies that the correct events were being called, but what is the purpose of writing the status code? Isn't the event already being verified in the "normal" test?:

t.Run("normal", func(t *testing.T) {
	t.Parallel()
	h := setupMore(testSetup())	var beforeCalled, afterCalled bool
	var beforeHasValues, afterHasValues bool
	h.ab.Events.Before(authboss.EventAuth, func(w http.ResponseWriter, r *http.Request, handled bool) (bool, error) {
		beforeCalled = true
		beforeHasValues = r.Context().Value(authboss.CTXKeyValues) != nil
		return false, nil
})

It's probably testing the code to prevent panics since http.ResponseWriter's normal Go HTTP Server implementation panics if you set the status twice. It wants to ensure the status isn't changing.
