Not sure what you mean with "squaring off" but 3 points:

- the heightfield is generated with subdivision algorithm, that produces    
rectangular structures

- ingo's code uses horizontal/vertical movement and no diagonal.  

- HF resolution is only 256x256

maybe one of these is the reason for your observation.
