That's not perfect pitch. 90% accuracy in pitch recognition based on memory retrieval is not perfect pitch. As for the bunch of comments here claiming they acquired AP at adult age for "only" one or two notes: that's not perfect pitch either. AP can't be acquired at adult age - your brain only learns to recognize pitches during your neural plasticity phase as a baby (provided it's exposed to enough variety), just like it acquires speech and color-discrimination. Also, AP is not a party trick. Not having it is akin to being color blind - even if you could "remember" what colors are supposed to look like, you would _still_ be color blind.

That the article's abstract and researchers are willing to claim the opposite despite their own evidence : this smells like butt-hurt denial.
