You are completely right.
It is preferable not to have the DHT22 on the board, the slight heating of the board components influences the readings of the sensor (especially if the receiver is placed inside a box).
In my systems I always use an extra connector (4pin KF2510 as you said) for the DHT22, and connect it with 10 to 20cm wires.
Usually I glue the back side of the sensor on the outside of the project box, this gives me more accurate readings of ambiente temperature / humidity.
The most right connector with the black, yellow and red wires goes to DHT22.
