First of all, jargon aphasia is always related to damage in the temporal lobe (particularly, in the Wernicke's area).
Now, given that the interviewed's speech presents nonwords like "bick", "chpickters" or "carfter", it is most likely that they were dealing with a neologistic aphasia, this is, no phonological relatedness to actual words that would reach the meaning intended by the speaker, but would resemble, at least phonetically, to others contained within the linguistic community.
