Is not a natural language (NL) proof a demonstration of mastery and understanding?

If you understand the Lean, then you can create a NL proof. The LLM clearly doesn't understand the Lean code it produced.

I guess I misunderstood the paper, that natural language proofs are not mastery/understanding because they can be ambiguous, miss-interpreted. Natural language can be misinterpreted enough that it is not a given to be correct. And AI was misinterpreting what a human meant in the ambiguous natural language.
