I think they’re getting at the fact this design would generate massive amounts of torque steer. With the motor input vertical, any rotation will also try and change your steering direction.
Driving the streering wheels exerts a force on the driving surface. That causes the steering wheels to have a tendency to toe in.
Looking from the top, you could run the motor clockwise on the right side and anti-clockwise on the left to cancel some of that, but the motor has very little leverage compared to the wheels.
