So basically, this is evidence that:

1) It isn't necessary to max out Uchiha ocular power before the Rikudou chakra fusion takes place.

2) Asura unlocking Rinnegan would first cause the Sharingan, then a Mangekyou Sharingan to appear, before the Rinnegan (think Obito awakening Mangekyou from a 2-Tomoe Sharingan).

No, I don't believe we have evidence to completely throw out everything we learned before. Especially when the only three on-panel examples of Rinnegan manifestation occurred in EMS users.

Rinnegan without Sharingan riding along isn't supported.
