\Safe\DateTimeImmutable comparison not correct

[kunicmarko20]

<?php

require_once __DIR__.'/vendor/autoload.php';

$timeLimit = \DateInterval::createFromDateString('2 hours');

$safeDateTime = new \Safe\DateTimeImmutable();
$phpDateTime = new \DateTimeImmutable();

\var_dump($safeDateTime->modify('+3 hours') < $safeDateTime->add($timeLimit)); // true
\var_dump($phpDateTime->modify('+3 hours') < $phpDateTime->add($timeLimit)); // false

Given this snippet, I would expect that both are false, but when using \Safe\DateTimeImmutable I am getting true.
