Kz, I see what you're saying about the two hallways (and looks like even those hallways utilize space with what looks like closets along the exterior walls though not sure what the dashes mean, sliding doors?) but having lived in a unit similar to this but with the traditional design of bedrooms off the living room, the separate hallways free up space in the bedrooms and living areas by not having the usual doorways leading from living room to bedrooms on either side. Total use of wall space to arrange furniture and especially in the bedrooms, no doors for closets either. One door, that's it. Very functional.
