Armor and evasion new mastery

Hi i am a xbox player who doesnt get expansion yet
There is a new armor and evasion mastery granting bleeding immunity if equipped helemet has higer armor than evasion or poison immunity vice versa

1. Is this mastery working on only hybrid armor and evasion helemt?
Or is it working on armor only helemet for bleeding immunity and evasion only helemt for poison immunity too?

2. If new mastery only works on hybrid helemt, does iron reflex node hinder/negate this new mastery?

My understanding is that it just compares evasion and armour values of the helmet. It should work even on pure ES helmets with benchcrafted + flat evasion on it (immune to poison). Iron Reflex doesn't affect the values on your gear.

unfortunately, for some reason, only 1 option works, if the armor is equal to evasion, then nothing.
