To be clear, the number of satellites you are showing has zero to do with "connectivity". All satellites do are provide a GPS signal to the drone. That is used for position stabilization. They have zero to do with the control and video links.
On the ST16(S) satellites locate the controller. Used for follow me, etc.
On the H/H+ satellites control positioning augmentation. You can fly with GPS off.
The reason for control lag in the environment where the pictures were taken was no doubt due to foliage interfering with the 2.4&5.8 GHz control and video signal along with some path distortion due to the water.
BTW - freaking awesome shots!!!
