This is a sketch from a page of Ontario Building Code training workbook, which is about OBC Division B, 3.2.8.9.(7), and 3.2.8.9.(4) & (5).

What does "FIRE EQUAL TO THAT OF FLOOR FOR PORTIONS NOT WITHIN THE ATRIUM" mean?

I could not find the clause about the required rating of the fire separation as shown: “equal to that of floor for portions not within the atrium”. Could you please show where the code describes this requirement?
