It's well-known that this algorithm doesn't have a perfect matching rate. It'd be easy to presume that any false positives are not erroneously tagged images, but the error rate of the underlying algorithm, if all the images were tagged correctly. Who would know?

IIRC Wired reported the algorithm "PhotoDNA" worked around 99% of the time a number of years ago, however newer algorithms may be fuzzier. This is not the same algorithm. And even "PhotoDNA" appears to change over time.
