Rey doesn't get why he's nodding approvingly. That last shot was terrible compared to her earlier ones, and she still doesn't feel the difference between using the force to help her shots and not.
But since he all he says is "Another one," she doesn't question his approval. She remembers how that previous shot felt, tries to understand the relationship between that feeling and how wide her shot went. Her next shot is ...
... only a marginal improvement. Her brows furrow and she is clearly Displeased. But Rey trusts him, and she has an iron will (usually. It's iron, not infallible). So instead of questioning him, she continues firing, shot after shot, taking time to try & figure out for herself what she's doing wrong, why she's still missing. It's how she taught herself basically everything she knows, really, since she didn't have a teacher. (She may need a little reminder that she doesn't have to figure everything out for herself.)
