First off, i think that Hamura's kids never had such a feud and so no transmigration cycle exists for the Moon-otsutsuki and Hyuga.

But i think what happened is that Toneri's people have a different Byakugan than the Hyuga, one that seems to be able to passively draw nature energy. because:


 * It makes no sense that (hyuga) byakugan sealed in the orb somehow contribute to it's continued existence, unless they too can draw nature energy.
 * The Tenseigan itself seems to control nature energy in some form, both in the way Toneri could draw power from the sun and from the way the Energy vessel worked.
 * It makes sense that the Moon-otsutsuki would seal away their eyes: if it drew too much nature energy, they either go insane (see: Jugo) or turn to stone (See: Sage toads) or straight up die (see: Curse seal).
 * It makes sense that if Moon-otsutsuki naturally draw energy, they can still sense their surroundings as if it's sage mode. Why else have elaborate drawing and structures when you're all blind? Because they could see via their "sage vision".

Lastly, i think that Toneri did in fact, NOT awaken the Tenseigan. Rather, i think that he used his natural power (natural energy absorbtion), his access and apparent connection to the Tenseigan energy vessel, to channel it's power through Hanabi's byakugan. Thus we get a parallel to the Gedo: Toneri pre-byakugan could interact with it in a weak way. With Tenseigan, he had full control and could channel the energy vessel's power and control the movement of the moon.

This is why the Tenseigan faded from his eyes: It wasn't really there, it was his Energy Vessel connection. It's also why the Byakugan at the end encapsulate and absorb him: the connection was still active.

(whether you can consider what happened to Toneri as "awakening tenseigan" is a matter of discussion, IMHO).

It's just one of my explanations, but i wonder if this is the path of least contradiction. In essence, Hamura sealed his Tenseigan dojutsu in the Energy vessel, and Toneri channeled it through Hanabi's eyes
