Not exactly a 'skinny' carrier. To keep weight/ring gear thickness down, at the gear break, the mounting surface for the ring gear is moved closer to the center of the carrier for the smaller pinion head. The thick gears are not stronger, there is the the same amount of teeth contact which is your main strength after material type.
Yes high pinion is the same as 'reverse' gearing. Once the pinion is moved above the center line of the diff, the helical cut of the gears are reversed.
