Yeah, that was strange. But it is probably a recognition of the relatively high probability of false positives on a per-picture basis with the system they've built. Having the threshold so high is probably necessary to ensure their stated false positive rate given the implementation (something around 1 in a trillion according to another article). But still, publicizing a hard number like that seems counter productive to the goal of keeping child porn off of Apple systems.
