There's nothing ignorant about asking if you don't know.
AWD's don't allow tires to slip when you overload the transmission by launching hard, this means all the stress goes into the transmission - when you overstress something like this which doesn't have a means to dissipate the energy through tires spinning or similar, this energy displaces to other areas.
Hard first gear launches will sooner than later destroy an AWD transmission whereas using a roll from first and pulling hard through second and first will be gentler on the transmission and net you better acceleration when your engine is up to revs.
