You're making a wrong connection, yes. Gengetsu's water is oily, that's why his hydrification is oily and that's also why his water clone is oily. But that doesn't mean that there's a connection between hydrification and the water clone. The hydrification is no parent technique of Joki Boy, but the clone can use it, of course.
