Prevent a form from being submitted javascript why is there an obvious false statement returning true?

<script>
function someFunc() {
    if (1==2) {
        return true;
    } else {
        alert("Not submitting");
        return false;
    }
}
</script>

This is from stackoverflow here

prevent form submission (javascript)

I want to know what the purpose of the obvious false statement 1==2 returns true is for?
