There are two different issues.  One is concept, the other is terminology.

Noting when a message makes it to the recipient, rather than merely being 
deposited into the recipient's mailbox, is the key conceptual point.  It is 
an essential distinction, because there is a significantly different sense 
about the recipient's "involvement" in the message.

In non-computing life, we refer to both situations as "delivery", but we 
use different qualifying language to make clear where (or to whom) the 
message was delivered.

Note that POP is a DELIVERY protocol, not an access protocol.  From a 
formal standpoint in email architecture, picking a message up with POP 
effects final delivery.
