> There are many reasons why others might not find what you wrote sufficient to understand it. You boss ran it through AI for a reason and that reason was most likely because it the document was not understandable or perhaps confusing.

It could also be because their manager is less technical. It's not unusual in my life for a PM to try to "rephrase" or restate things I've written in order to make them "easier to understand" in a way that in fact falsifies them or makes them more difficult to understand for the people who will actually have to work on/with it.
