Yes, the same person could be listed in two seperate locations on the Census for that location. The Census was not all taken the same day by the same person. If the person was listed in there home, and later was visiting family or whatever caused them to be in a different location, they were listed as residing there at that specific time. So as stated in a prior answer by Kim he may have been hospitalized and listed there, and also in his home prior to going in or after his release from the hospital.
