Countess,
The police mentioned 'inconsistencies' in the woman's story so your hypothetical examples may actually be close to the truth - not sure.
The CCTV, if it stood alone, could/would still be evidence that countered the womens story. A hypothetical prosecution might try and undermine that evidence, or inference from it, by introducing the model of post rape erratic behaviour. This might make it neutral evidence or it might still undermine the plausibility of her story. It would be a matter for the jury. However in this case there is other evidence that is also compatible with his story such as her diagnosis and her texts.
On the other hand, had there been CCTV evidence that showed her as irritable, pushing him away, staring daggers at him, turning from him, resisting kisses etc, then for sure a hypothetical prosecution would be using that as evidence against him. And in turn, the defence would try to explain away such evidence and it would be for the jury to consider the merits of such evidence.
Whatever conclusions a jury came to, it would not 'automatically mean' that a single juror had bought into a rape myth.
