I have to say that after seeing the grass cloned out I actually feel that it added something to the original. It helped define and confine the space in which the scenario is playing out.
After looking at both versions for a while, Walter, I'd have to conclude that the corrected version is the better one. Seems to me defining and confining the space in which the scenario is about to play out reduces the ambiguity. But I realize that opinions may vary.
