More than one inside global to one inside local. i.e. two public's ip's
coming from two outside nat interfaces to one inside local ip (private ip,
etc).
It also (based on routing) allows one private ip to use more than one public
ip).
So by "extending" the connection you allow more than one option for the
translation.
I often use this in the real world when one private ip'd server is going to
receive email on two providers each providing real ip's to the customer.

Subject: The ip nat optional extendable
So for all you smart guys out there I've got a question for you.
The optional command "extendable" has a definition on Cisco's website
extendable
(Optional) Extends the transmission. So what in the world does that
mean? What does this optional command actually do for nat.
I've been looking and don't really see anything explaining how it helps
out NAT or what kind of situation you would or would not use it in. I
know I've seen lots of examples with it in them and that it's needed in
many of them but why is it needed.
