Thats a pretty fundamental confusion, but it's forgivable due to bad naming. An address isn't a destination in Bitcoin, it functions more like the serial number of a bill (though the system is able to handle duplication). It would be better thought of as an invoice number. You don't expect to reuse a different invoice number of separate payments.
