Because of the assumption that he had met the Drs McCann, I think Mr Amaral must have realised at some point that it really did not suit his narrative that he did not have first hand knowledge of the couple he was accusing of a most heinous crime ... so from sofa to sofa ... interviewer to interviewer ... it was necessary to portray his version of the 'truth'.
Possibly he should have gone for a less sensational title for his 'penny dreadful'... then he might not have had to engineer suitable sound bites giving himself a role he never assumed while in charge of the investigation.

Q - You have a long career as an investigator, years in which you have faced criminals and innocents. What do you see when facing the McCanns?
A - They are two persons with much fear. I do not know if they fear to be discovered or fear the police of an unknown country.
Q – It was said that Kate was very cold. But I’ve seen her cry.
A - So did I. She is not cold. There was a moment, in a meeting with them, when we set out the sofa theory. Kate put her head down, looking distant, and, after a few seconds, she looked up again as if nothing had happened. She looked like she was escaping from the role that she was interpreting.
Q - When you raised the hypothesis that the girl might have died after falling off the sofa, did Kate McCann answer?
A - She did not answer, she just dropped her head for a moment, as if she was about to faint. She had an emotional collapse that lasted just a moment.
