I'm pretty sure it's because Cambie switches there from the wide boulevard to the narrower street through the section to Broadway (where the shops are). To build a wider, shallower, cut-and-cover section would have effectively closed the entire street. The deeper but narrower slot for stacked lines meant less disruption on the surface. As we know, that didn't exactly work out well for businesses, so it's good to remember it could have been worse! The changing grade, and the benefit of having the tunnels nearer the surface for the Broadway station (and therefore leaving space to thread an east-west route underneath later) put the tracks side-by-side in Broadway-City Hall station. You can see just how huge the excavation for the station was
here.
