I think their point is that the movie didn’t give much attention to her role, which doesn’t have anything to do with her gender. It’s generally considered to be bad form to refer to someone using their deadname even if you are talking about a period when they were using it.
We should not make assumptions about someone’s gender identity before they “transitioned”. She was living as a man, but we don’t know how she identified at the time.
