How 'morerealistic'?

[WJTW]

I have yet to get it to work, but that is not the point of this thread.
What I am curious about is: How more realistic is 'sabermorerealistic' when compared to 'saberrealisticcombat'? Does the parts fall off more realistically, and not still animate ("it's alive!") with the main body, or is it the same as the JK2 one, but with a fancier name?

But then, the 'more' can also be compared to the regular, nondismemberable version...

From my memory of JK2, this is more realistic. The sliced off parts do still move like the main body but they can now be sliced off in more places. They also seem to land on each other instead of clipping.
