One of the problems with discussions about what happened in all these scenarios using the information in Harry's book is that he himself said in the book:
Whatever the cause, my memory is my memory, it does what it does, gathers and curates as it sees fit, and there's just as much truth in what I remember and how I remember it as there is in so-called objective facts.
Harry's ghostwriter also shared the following quotes on Twitter last week in reference to Spare/Ghostwriting from a book by a memoir writer:
He posted three quotes from Mary Karr's The Art of Memoir. In one, Karr writes, "The line between memory and fact is blurry, between interpretation and fact. There are inadvertent mistakes of those kinds out the wazoo." In another, Karr writes, ""Neurologist Jonathan Mink, MD, explained to me that with such intense memories as David’s, we often record the emotion alone, all detail blurred into unreadable smear."
So this is fine - we are getting Harry's raw emotions - how he felt about things that happened to him - and no one can dispute his own truth about that - but these memories are not always based in reality or facts - it doesn't matter so much in some recollections such as whether it was a Playstation or an XBox, or where he was when he heard the Queen Mum had died, or that he's directly descended from Henry VI etc. It's weird these things weren't fact-checked but it's not affecting anyone else.
But when the memory is accusing someone of assault (William), elder abuse/control (The Bee - Sir Edward Young) or supporting racism (Kate advising him to wear a Nazi costume and finding it hilarious) then it's unfair and awful to put out these 'memories' as factual things which happened.
