What is this interaction?

In 7.4.5 the head rush path i got to CGR. When i went in with Medusa i die as soon as i land a hit on him. Reading the nodes this could be caused if buff is nullified but Medusa doesn't nullify. When i hit CGR he gains armor break and Medusa might be breaking the armor but is it counted as nullified?

The re did path with apoc
Armor break is treated as a nullify when you're being punished for nullify, but nullify immunity won't protect armor ups from it...
