Autism assessment - ADOS Module 4

I recently went through the ADOS module 4 autism assessment and am wondering what they were looking for.  It involved some story telling (around pictures of flying frogs and some objects to bring in to another story), looking at and talking about a kind of child's map and explaining how to brush your teeth.  The thing is, I'm 55 and can, I think do these things rather well.  I'm perfectly used to making up bedtime stories to children and explaining everyday tasks.  I also have a great deal of experience of masking and surviving in the workplace and I'm fairly sure my responses to these questions and tasks would have look at whole lot more autistic when I was in my teens before I developed a whole rake of coping strategies.  I'm the same person, however.  Can I be confident that the assessment result can be reliable?
