That person is still a beta listener. With written fiction, you can ask your beta to just do a spelling and grammar check or you can ask them to identify character development and plot holes in the story. Podfic works the same way.

Your beta can be involved as much or as little as you choose. You can ask, "Are there any repeated lines and weird noises?" up to, "Does this music work for the emotional impact that I want?"

(I once did an beta for someone, where I listened to her podfic and periodically made audio corrections within the work. She had never made a podfic before and needed a lot of help.)

It's all up to you.
