It can be either way around.
On the IAQ, a few things it does.
Say for an example on mine. I have it set at 45% humidity, and cooling set at 76˚.
It's a hot dry day, house is 43% humidity, the house gets to temp, the IAQ will turn on the A/C to cool the house, and the blower will run at full speed.
Then you have company in the house, or doing laundry or dishes, the humidity in the home climbs up to 46%, the IAQ then tells the blower to slow down and remove the humidity.
The house temps reach the IAQ set point for temp, the humidity is still at 46% **, the IAQ shuts down the A/C. and waits for the next call for cooling or dehumd.
You still got laundry going, house is still at temp, but the humidity rise up to 51%, now the IAQ will start the A/C and run in Dhumid mode, the blower stays at a slower speed untill the humidity is below 50%, or if room temps falls below 3˚ of set point.
**= I did not mention in my last post that the IAQ will start the "over cooling" if the humidity is 5% over set point.
