I did this few days ago too. It might be "temporary" but not bad, I mean temporary as in as long as the new one actually lasts, so 100k? and then code new cat again. Small thing to do..
I think ECU has no means to know the state of cat unless there are sensors after the cat.
I think it is all approximation and calculation. ECU knows how many regen cycles that cat can handle or roughly how many miles it can last or how much nox ppm it can take. That's why is says "aging" not "aged/clogged/needs_replace".
So encoding nox cat replace is probably identical result as actually putting a new one in AND encoding. Difference will be only in emissions.
Again, the above is what I assume/think.
