The proposed amendment to the Highway Code will say "[cyclists

If you read the story, the cyclists moved into single file to let the van driver past. Why they then decided to pass by at high speed very close while leaning on their horn, only they will know. Totally unnecessary behaviour.

You are deliberately avoiding the point about not obstructing (which
happened when the cyclists were riding in parallel rather than in
series, totally unnecessarily).
