Here’s my take on the scene. By removing some lines it allows Rey to “take it upon herself” to go to Exegol. She doesn’t need Luke telling her what do to.
Saw this after my last post. The url appears to be invalid.
It’s up now. Was still uploading. Maybe I’m a little biased to my own opinion on this but I feel it is a stronger character moment for Rey to want to go to Exegol on her own instead of Luke guiding her and instructing her to. What does he care if she takes both sabers. It just feels like another audience pandering moment. Let the characters think and make their own decisions.
