"ip address"/"ip unnumbered" for Tunnel interface

I have a following tunnel interface configuration:
C1841#sh run int tu0
Building configuration...

Current configuration : 153 bytes
interface Tunnel0
 ip address
 keepalive 5 3
 tunnel source FastEthernet0/0
 tunnel destination
 tunnel checksum


Am I correct that IP address is used as a source IP address in the GRE encapsulated IP header only in case the packet is originated from the C1841 router itself?
