It seems like you are loosely comparing two booleans. Considering using the strict comparison === instead.

            return false;
        }

        return ($this->getTargetNode()->isRoot()) ?
            false : true;
    }

    public function isSourceNodeAtRequiredPosition()
    {
        $sourceNode = $this->getSourceNode();
        $targetNode = $this->getTargetNode();

        return ($targetNode->getLeft() == ($sourceNode->getRight() + 1) &&
                $targetNode->getParentId() == $sourceNode->getParentId()) ?
            true : false;
    }
}
