$leftTotal is of type hiqdev\php\billing\charge\ChargeInterface, thus it always evaluated to true.

            // If we had both charge and left hand total charge – pass comments and events that were probably generated in left total
            if ($leftTotal->getComment()) {
                $charge->setComment($leftTotal->getComment());
            }

            $events = $leftTotal->releaseEvents();

The method releaseEvents() does not exist on hiqdev\php\billing\charge\ChargeInterface. Since it exists in all sub-types, consider adding an abstract or default implementation to hiqdev\php\billing\charge\ChargeInterface.

            if (!empty($events)) {
                foreach ($events as $event) {
                    $charge->recordThat($event);
                }
            }
        }

        return $this->unique(array_merge($leftCharges, $rightCharges));
    }
