SOT Question

I’m on a fully updated 14PM with AOD in use. When I look at my battery usage it says (for example):

Screen Active 7h 27m Screen Idle 3h 18m

Does this mean the screen was in use for a total of ten hours and forty-five minutes, of which three hours and eighteen minutes was AOD just sitting there or does this mean the screen was in use for seven hours and 27 minutes out of which three hours and eighteen minutes of it was AOD just sitting there?
