The Advantage of Using "getString" in tabs array?

Hey block dev's, when I'm setting up tabs in my block form.php, whats the advantage of using the getString method over just static typing the names?
Example, the way I've been doing it:

echo Core::make('helper/concrete/ui')->tabs(array(
    array('items', t('Items'), true),
    array('options', t('Options')),
    array('layout', t('Layout')),
    array('colors', t('Colors & Padding'))
));

And the way I've been seeing the more experienced developers doing it:

$getString = Core::make('helper/validation/identifier')->getString(18);
$tabs = array(
    array('form-items-' . $getString, t('Items'), true),
    array('form-options-' . $getString, t('Options')),
    array('form-layout-' . $getString, t('Layout')),
    array('form-colors-padding-' . $getString, t('Colors and Padding')),
);
echo Core::make('helper/concrete/ui')->tabs($tabs);
