Went in-game to test it myself, seems to only effect Priestess.
Click Priestess - *Greeting VO plays*
Click "I need spiritual help."
Click "No thanks, I will pass for now" - *Greeting VO plays * = BUG
It's going to sound odd if she greets players every time you return to her main menu, especially since if they've exited the Spiritual Help menu, they're likely "on their way out" and now the Exit VO will likely overlap with the mis-triggered Greeting VO.
Here's an example:
