When the vehicle is rolling towards the caster, the caster is much
closer to the drive wheels, and they have a lot more leverage
against the caster to position it where they want.
When it's rolling away from the caster, the caster is so much
farther away that it's harder to leverage it into a straight
position.
This is just a guess though.
