woocommerce_products_will_display() function issue

I use woocommerce_products_will_display() function to validate HTML part, that will be show on the product-archive page. It works but, has an issue with the custom taxonomy, if custom taxonomy has child, and child has more than one product woocommerce_products_will_display() return false.
I think the problem is in this part of code

if ( empty( $term->term_id ) || empty( $term->taxonomy ) ) {
    return true;
}

Why return true if the taxonomy is empty?
If I change it to this

if ( ! empty( $term->term_id ) || ! empty( $term->taxonomy ) ) {
    return true;
}

all works fine.
