Is a truly "anonymous" one-time shopping cart possible?

I'm putting together a passwordless checkout for a client that sells an item usually sent as a gift to others.

During testing I've noticed that if I go back through the checkout and use the same email address as a previous order, then the stored address for that order is retrieved, and whatever details the customer has entered in the customer_create_passwordless.html are discarded.

Is there anyway to configure the checkout to be "anonymous" (for want of a better word) so that even if an existing email address is used it doesn't retrieve any address details from the database, but instead always uses the entered address?
