Perhaps the local IP is the IP which is the destination of the
forwarding. If this router is a simple SOHO device, it may only support
a single IP on the public Internet side, and that IP would necessarily be
the IP to which some outsider would connect.
In other words, your router is forwarding from sourceIP to destinationIP
where sourceIP is the public Internet-facing IP of your router and is therefore not configuration where one configures the IP forwarding. Only
the destinationIP - which is one of many possible IPs on the LAN side -
is configurable where one configures IP forwarding.
Of course, this is just a guess given that I know zero about what router you're using.

In other words, it is the original *destination* address, and calling it
"sourceIP" is misleading.
It is the destination IP of a connection being forwarded, but it is the
source IP of the forwarding. I agree, though, that there are multiple contexts which can make this confusing. That's why I tried to explain in
And, of course, all this remains merely a guess as to how the router
might be working.
