Да млииииин, ну как же еще объяснить... ну абсолютно все равно что бы не возвращал dispose() к условию в if() это вообще отношения не имеет! При чем тут универсальность кода!? Я уже объяснил зачем там этот if.
Вот нашел какой-то промежуточный вариант кода, надеюсь, это как-то поможет понять зачем это было нужно...
