The zero factor on the orbital velocity means that the probe is moving in
a purely radial direction, i.e. straght out from the Sun. The planet, however,
sees it as moving at orbital speed away. After slinging around, it is moving
at the same SPEED with a different VECTOR. So, from the planet's point of view
it comes in one way and goes out the opposite. From the Sun's point of view,
it goes in with no orbital and come out with 2 times the planets orbital
velocity.
