It is more than that.

This is what make remote debugging possible. It is impossible to do interactive remote debugging over a ultra low bandwidth link. If everything have static address and deterministic static, you can have a exact copy on ground and debug there.

Interactive debugging is apparently possible and was reportedly done on Deep Space One mission. One of developers involved frequents HN I believe.

Kind of. That took hours of not days.

A local exact replica with deterministic state save lots of time.

You can also have deterministic dynamic - the satellite could transmit its dynamic state (a few bits signifying which memory cells failed) and then you proceed deterministically on the ground.
