Hollowkeeper interaction with freeze

So in a video Kripp basically claims that hollowkeeper prevents you from actually getting completely locked in place when you are frozen. Now i tested this out a bit and from what i can tell thats not true, you can get rooted in place same as before if frozen. Anyone know if this is how its supposed to work or? He makes a pretty big deal about how good this node is, i tried playing with it a bit and not really sure about it tbh, doesnt seem worth the high investment cost of 8 passive points.
