Sorry, I am basing this on USDM spec cars. It would be kind of dumb for the ECU not to keep all the updates to the memory for things like recalls and such when you changed the battery. That would be a major liability for the manufacturers! Hence why when they do flashes like that here in the US they are more or less permanent even if you change the battery.

At long last I had the reflash done earlier this evening. The forester drives the same afterwards, but when putting in the clutch to coast towards red lights I experienced no revving. I'll followup in a week after I've had a chance to drive some more.

And not an idle rev (dealer called it idle fluctuation) to be seen. I call the problem fixed.
Curiously just today I received email regarding Service Program WVN-24, regarding a ECM reflash and one-way valve removal to prevent possible catalytic converter damage. I wonder if the reflash I received four days ago covers this? Annoying.

My 09 Forester X 5-speed does the exact same thing. It doesn't settle down to idle until the vehicle stops. It's impossible to modulate between on throttle and off throttle smoothly between about 2000 to 2500 rpm.
I hate the dealership where I bought it and had it serviced for the first 40k mi. I'll take it to the other dealership in town next service and see what they say.
P.S. It doesn't do it when the engine is warm but not yet up to full temp. Maybe a colder thermostat would help?
Wish Subaru would publish something so I would know for sure.
