I don’t know if you have noticed the word redefine. I don’t understand how the disabled opcode is redefined by OP_SUCCESS.

It's very simple, the script interpreter starts with evaluating the output script being spent and when it is version 1 witness script it uses a different route for evaluation. That way it cutes the script in another method that checks the OP code to be in a certain range (including those disabled OP codes) and considers them OP_SUCCESS and simply returns true when they are in a Taproot script.
In a way it is bypassing the old evaluation where these disabled OP codes are rejected.

I read the code, but I didn’t understand what is the purpose of this upgrade of OP_SUCCESS? Can you give me a detailed explanation? Thank you
