ASA5525: SLA ISP failover config-- Correct NAT config?

Hello.

Inside an ASA5525 I am implementing an SLA config so that when ISP1 fails, default traffic will reroute to ISP2.

It seems that in this config I need to add an additional NAT statement, such as...

  "nat (inside,OUTSIDE2) after-auto source dynamic any interface"

...that will achieve the above intent, and also will exist in harmony with the existing below NAT statement...

"nat (inside,outside) after-auto source dynamic any interface"

Since the rerouted traffic will be using OUTSIDE2, does that mean that there is nothing special needed here, that the below config will achieve the intent, and will not break anything?

nat (inside,outside) after-auto source dynamic any interface
nat (inside,OUTSIDE2) after-auto source dynamic any interface

Thank you.
