Perhaps some of these simply turn null move off in positions with low material, and what you might be seeing is a difference in the material threshold between the different programs. Everyone has their own method of dealing wth low-material zugzwangs, but I think that it is wrong to assume that overall endgame strength is somehow dependent upon handling these zugzwangs properly. bruce
