By default, when customers accept the thank you page upsell, the main order and the upsell order are cancelled and merged into a single order shipped once. However, Shopify tracks all 3 orders as successfully paid separately. If you enable this option, only the main order and the upsell order will be tracked in the sales reports.
That means you can display an upsell in a product page depending on what's in the cart already. Cart rules are also available if you use the Manual Setup and implement the upsell snippet directly in your theme files.
This will also works for the cart rules. For example, upselling the subscription if the one-time product is present inside the cart.
