Well, I don't
Imagine you have a range 3 city. Your army is two tiles away to reinforce it.
The ennemy capture it: your army is now in ennemy territory, cannot run to the city to capture back, and is opened to immediate attack as the ennemy can use road bonus...
The ideal solution would have been to implement it differently: a city which is not pacified (still some resistance in it) should have NO culture (it controls only the city) until it is pacified, then you get back the whole culture.
It stays during a few turns in a no man's land.
