Regarding different answers.
Think about a recent situation in your life, an incident, funny moment, etc.
Now think about the first time you relay it- say to the first person you see after the incident , a neighbour.
Then at school pick up, you tell it again to a couple of parents.
Then, a week later, you tell it to a group of friends at a meal out after a few drinks.
The next month, you tell the same story to a friend over text.
You will not have told the story succinctly, using the same detail, order of event unfolding, pauses, words etc....because you are not a mechanical robot. Instead, you will have given a version of the story, and each person you told it to would have responded slightly differently each time and so the conversation would have taken a few different turns, it will have brought up new bits of information, you will have been triggered to remember things in a slightly different way. And you may have new realisations, new connections will be made in your mind etc etc.
So pedalling out the same sentence that 'he changed his story' does not in anyway dilute his actual experience, he is living this in real-time. Recall can be difficult, excruciating most probably in this case. It matters not about the specific minute details because these men are recounting their overall experience of being groomed and abused. It was 'loving' and they thought at the time it was consensual.
Micheal Jackson was a peadophile. Whether he was dead or alive, it is only now that these men can reflect on their experience for what it was.
