It is perfectly possible for anyone to do anything for any reason. I believe the definition of autogynephilia is used to claim that everyone who transitions does it for the wrong reason because everyone who transitions is defined as mentally ill and motivated by their mental illness. I am going to invent a disorder I call autogynephiliaphilia. It defines the mental illness of people who embrace the idea of autogynephilia because they love to hate TG and TS people. I think this disorder is far more likely to exist than the one for which it is named.
It's possible for TS people to regret their transitions for good reasons. It is also perfectly possible for people who regret their transitions to regret them for the wrong reasons, but let’s not try to overanalyze other people’s thoughts and behavior. If anyone believes they have made a bad decision then they must cope with the consequences like we all do. There is no moral imperative to stop TG people from making bad decisions because there is no moral imperative to stop any normal person from making bad decisions.
