Yes, your'e right, they do start at random direction, but the outlet is made somewhat centered, so it doesn't matter which way the rotor spins. It decreases some of the pump's abilities, but that's the only way (without the tweaks like Volenti did) to ensure the direction of flow regardless of direction of rotor spin.
Dunno how to explain it better, there was a thread concerning this...:shrug:
