How can move/use one element at different position? In Magento 2.2.3

Question

<move element="product.info.stock.sku" destination="product.info.addtocart" as="product.info.stock.sku.old"/>
<move element="product.info.stock.sku" destination="product.info.addtocart.additional" as="product.info.stock.sku.additional"/>

I have tried the above code in catalog_product_view_type_simple.xml file and getting as

<?=$block->getChildHtml('product.info.stock.sku.old',true);?>
<?=$block->getChildHtml('product.info.stock.sku.additional',true);?>

But only one work at a time, actually I want to move sku in simple product which has options or not.

You can not move one element to 2 positions. It doesn't have a clone function or somethings. So in order to do this you will need to create a second block for this, like:

<container name="product.info.stock.sku.copy" label="Product auxiliary info" htmlTag="div" htmlClass="product-info-stock-sku">
    <block class="Magento\Catalog\Block\Product\View\Description" name="product.info.sku.copy" template="Magento_Catalog::product/view/attribute.phtml">
        <arguments>
            <argument name="at_call" xsi:type="string">getSku</argument>
            <argument name="at_code" xsi:type="string">sku</argument>
            <argument name="css_class" xsi:type="string">sku</argument>
            <argument name="at_label" xsi:type="string">default</argument>
            <argument name="add_attribute" xsi:type="string">itemprop="sku"</argument>
        </arguments>
    </block>
</container>

Use other names to avoid collisions.
