Marriage protection with a difference in Hawaii

Back in 1993 Hawaii's Supremes ruled that not allowing gays to marry was discriminatory. However, they didn't require the legislature to enact gay marriage. In 1998 a marriage protection amendment was passed and the ruling by the Supremes was irrelevant. But this amendment is not quite the same as all that have come after. It says, "The legislature shall have the power to reserve marriage to opposite-sex couples." Which they did. However, it does not require such a law and does not prevent the legislature from changing its mind. And they appear ready to do exactly that.
