What I mean is that in some rules, the antipattern might match too much, and prevent the rule to fire in cases when the antipattern just partially matched. I had such cases – your antipattern is quite specific but it might easily happen with some POS tag pattern that would not match but it should (just imagine that due to skipping you match very remote parts of the rule).
So I would then just limit the marker to the first token or the last one just to be on the safe side in such cases.
