It doesn't matter what happens on the other parts of campaign map, at cities the process is different. When you sally forth the battlefield is centred around the city, regardless of the fact that your army is attacking (where usually it is centred around the defending army). If you had attacked with your reinforcement army then the attack does take place on the defender's square and your city army would join. But as you were sallying forth the battlefield is place around your city and your reinforcement army is not in range.
