I disagree that it is "actively impeding". The definition is very broad. Things like fake steals, fake bunts, etc. could even be lumped into this category if you interpret it broadly enough and decide it "hinders or confuses" the defense. My main objection is the thought that the batter could fake the bunt then pull it back legally but somehow looking back at the catcher makes it illegal.Not sure the definition leaves much room for opinion.
We play under USA Softball rules and their definition is pretty clear. Not agreeing with it does not mean it isn't a violation... If the batter is intentionally putting their bat in the sightline of the catcher they are actively impeding her from trying to make a play.
