Required Separation of occupancy S - B

In regards to table 508.4 of the IBC there is no occupancy separation required between an S-1 (Moderate Hazard - Furniture, etc) and a B occupancy.  Whereas, either a 1 or 2 hour separation is required for occupancy separation between and S-2 (Low hazard - no combustible items) and a B.


Seems to me that the table is in error and the occupancy classifications are reversed. 


Logically, I would think a rated separation should be in place where a greater hazard and fire load is located and the B occupancy above.


What are your thoughts?  Thank you
