Matching surveillance camera images is always possible no matter how bad the image quality is. The only matter is how many false positives show up.
Facial recognition algorithms always give their best matching candidates, with thresholds to skip those not quite matching ones. Your article makes it sound like no such results were produced at all, which is unlikely how recognition is supposed to work.

The pixel density is simply too low to even attempt plus the downtilt would also likely trigger a rejection. That's how facial recognition does work in practice. Even if the system would allow it, not only would false positives be enormous, you'd probably miss the match as well (false negative).
