[Risolto] Stock status doesn't change when order placed on 2nd language

Hi, as indicated in the title, the problem concerns the fact that if a product is purchased in a secondary language and the stock is reset, only in that language does the out of stock label appear, while in the rest of the languages ​​in the backend the product appears with an available status, although all variants have stock at 0. All the products on the site are of a variable type.

I have already found a thread relating to my request at this link: https://wpml.org/forums/topic/stock-status-doesnt-change-when-order-placed-on-2nd-language/ and have read it.

I would like to better understand what is happening and possibly whether the problem has been fixed on the new versions of the WPML + Woocommerce ecosystem plugins.

Inside the thread it is indicated to comment out a part of the "sync_stock_status_for_translations" function, in particular the "if ( $this->woocommerce_wpml->products->is_original_product( $product_id ) )" condition.
Can you confirm that this function checks that the stock_status is changed to a product in the main language of the site?
If so, why was this condition originally set? I would like to be sure that changing it as indicated in the fix does not corrupt part of the flow.

Thanks.

Lorenzo
