Rule 702.16n
Official source text from the 5 February 2021 Rules release
Some Auras both give the enchanted creature protection from a quality and say “this effect doesn’t remove” either that specific Aura or all Auras. This means that the specified Auras aren’t put into their owners’ graveyards as a state-based action. If the creature has other instances of protection from the same quality, those instances affect Auras as normal.
