Hi The ground wave (hopefully) travels a shorter path. The gotcha comes in when the phase shift is 180 degrees and you start nulling things out. That will play havoc on the “stuff” that works out the envelope shape for detecting the third pulse. Again, I didn’t design a from scratch receiver to do all this back in the 80’s. I just tuned my Austron over to another chain to see how it did and drew some conclusions.
