PayPal Express Checkout process missing step


I know I’m asking this question a bit late, but is there a reason why the PayPal Express Checkout execution flow has been implemented without the confirmation step (step 5 on this diagram) like expected by PayPal? Isn’t it missing?

I don’t guess this step is made mandatory by PayPal (eventhough it would be worth asking them) but it’s definitely missing in the user’s buying experience. Actually, the PayPal “Review your information” page says:

– “You’ll be able to see your order details before you pay” in the left “Your order summary” section

– “You will confirm your payment on [store name]” just below the “Agree and continue” return button

Like presently implemented, both these statements are just wrong! Might they not be deemed even abusive?

Wouldn’t it be a good idea to add this missing step in order to avoid any possible unnecessary dispute?
