I've encountered an article from The Independed:

12-year-old boy who transitioned to female changes his mind just two years later

Isn't it ambiguous, how old was he at that moment? Was he 12 when he transitioned to female or when he changed his mind?

The article itself clarifies this, but I want to know was the title ambiguous for a native speaker.
