Notional Boundary Analysis

In a situation where a notional boundary analysis is required, C/AS2 paragraph 5.2.9 states that analysis should be conducted separately for each firecell using the same notional boundary. However, in a case where only one of the two firecells contains a sleeping risk or exitway, we are only required to consider radiation in one direction right? In other words, in this scenario is it acceptable to set a notional boundary at 1 metre from the sleeping firecell and use the relevant factors for the non-sleeping firecell to determine the remaining distance separation? Just checking because I have had this queried recently.
