That might just be a UX issue. If the Exposure Risk Scan were instantaneous rather than ~1hr I think (optimistically) that the result page wouldn't be misleading as a whole. That said, I did confirm your observed behavior with securely random identifiers (in the off-chance that "Notareal Personxxx" is _actually_ sufficiently commonly used for testing that it was slurped up by data brokers).
