It may be that your first paragraph turns out to be true, but I don't think it is a given. At the point Kajsa embarked on the record, the Guinness requirements were much stricter than UMCA's (single bike, no drafting). When, after she started, Guinness subsequently recognised Kurt's record, Guinness got themselves into a bit of a pickle about what rules would be applied to Kajsa. Kajsa then agreed with them that she would continue her 'strict' version and has done since then.
It may be that Guinness will list records in different categories (e.g. drafting vs non-drafting), so we don't yet know how history will view the various attempts. Personally, I view Kajsa's attempt, assuming she goes further than Billie, as a 'moral record' in its own right and far from second best.
In some ways it is Alicia who is really caught between two versions of the record. She is following 'Amanda rules' but will be second to her in distance and although ahead of Kajsa, she will be under the more relaxed regime of UMCA.
