It would have to have evidence of destroying Concepts. Concepts are a higher-up form of existence, so not all EE erases it. For example, when Zenō erases multiple universes in DBS, they’re gone, completely destroyed. But people still know the Universes existed, and the Universes could still come back from Super Shenron- the concept of those Universes weren’t fully destroyed.
Now, say Character A has Immortality Type 8 (Reliant on something to live), and let’s say that Immortality means he lives as long as the concept of... Dogs exists. Character B erases Character A with his EE, permanently. This would obviously mean Character B can erase Concepts, as he just erased someone who lived as long as the concept of Dogs exists.
If Character A was reliant on Dogs living, however, then Character B’s feat wouldn’t mean Concept Erasure. It means he erased every Dog that was Alive, which is just some good Range.
I hope I explained that well.
