Thank you - corrected in the next version of this document.

You are correct - this is wrong and badly written. 

It is an identifier  for a specific assertion (e.g. this person was 
vaccinated; this  person was tested) rather than something tied to 
the person; it is inside the elements of arrays of such assertions
 about 'a' vaccination, test or recovery statement*.

We've tried to clarify this in the next version of the draft.

With kind regards,

* Earlier versions of the design called for a 'per event' identifier; e.g. 
  one for every shot in a sequence -- but while desirable for some of the 
  business rules countries wanted to apply on inbound - this turned out 
  to be impractical given the date available in practice).
