Since most of the vertical stabilizer is above the thrust line, you need right thrust due to the above-described effects.
What you have described is called the spiraling slipstream effect. If there was as much rudder underneath the aircraft as above, the left yawing tendancy would be reduced; however, it would be difficult to land with those super long gear required to keep that big chunk of airplane from scraping the ground.
