It might (or might not, let's see) be worth pencilling in a timeline of what Vixen's version of events during the rescue are.
As I understand it, her story varies from the version in the report as it includes an earlier flight by a Swedish helicopter, not necessarily Y64, which is erased from the public record. On that flight, 9(?) senior officers of the ship were rescued.
At some point during the rescue missions, Aftonbladet got a story of Y64 having flown earlier than officially recorded and of Svensson having rescued 8 people.
Also at some point, information about the identities of these 9 first rescued got to someone in Sweden who realised they wanted those people to be disappeared (for uncertain motives but let's gloss over that for now). This was someone who had the authority to order it done. Vixen said that it likely happened after the 9 had been moved to Huddinge Hospital.
Now significantly, the initial rescue plan was that to save precious time the helicopters were to take survivors to the nearest ferry. Two Finnish helicopters began carrying out this plan and landed 4 each, but the heavy seas made it too dangerous and impractical to continue and later rescues were flown directly to land, which took more time. As time went on the condition of those being rescued generally deteriorated and so taking them straight to a hospital began to make greater sense.
But Vixen's early secret flight was before this initial plan was revised, and before the Swedish helicopter crew had any idea the people they'd saved were to be abducted. So which ship did the mystery helicopter land the 9 on, and when and where were they transferred next, and how was their existence hushed up with so many people having seen them?
I appreciate there aren't going to be any worthwhile answers to this as it's not what really happened, but I thought it might be worth looking at its practicability.
