Cisco ASA NAT (any,outside) question

I am having issue with IPsec site-to-site branch-1 to branch-2 routing issue and i have following NAT rule. I read most of people saying use nat (outside,outside) so question is does (any,outside) means (outside,outside) also because any = any interface. am i missing something here?

nat (any,outside) source static obj-NET-PRIVATE obj-NET-PRIVATE destination static obj-NET-FOO obj-NET-FOO
