An amusing misprint in a paper on cognitive assessment

I'm afraid this is funny only for neuropsychologists. So here's what I just read in a paper presenting yet another comprehensive battery of cognitive tests for the bedside assessment of stroke patients:

(v) complex visual processing group (occipitotemporal network) including alexias, simultanagnosia, achromatopsias, prosopagnosia, simultanagnosia, object agnosias, visual hallucinations, illusions and delusions

Did you spot the error, and did you get why this is (sort of) ironic?
