Residential Safety Glazing

I have a question about the 2003 International Residential Code regarding saftey glazing in windows. Section R308.4 item #6 requires safety glazing in windows within a 24" arc of a door in a closed position. Exception #4 states that windows in walls perpendicular to the door in closed position are exempt from this requirement. So far this seems clear except that the IRC 2003 Commentary Figure R308.4 (4) contradicts this and shows windows in walls perpendicular to the door in a closed position do need to have safety glazing. Can you provide any clarification for this?

Thank you.

I am not sure if it is the same in the 2003 IRC, but from the 2006 IRC, Exception 4 to R308.4 specifies that the glazing in walls perpendicular to the plane of the door in a closed position, other than the wall toward which the door swings when opened, do not need to be considered as a hazardous location. When the door swings towards a perpendicular wall that contains glazing, even though it is perpendicular to the plane of the door, this area is considered to be a hazardous location and will need safety glazing.

Hope this helps.
