Power-wise, Indra's branch deals with Yin-release (that is, dealing with the barrier between reality and imagination) and Asura's with Yang release (that is, physical strength, reserves, longevity). Note that the Uchiha deal with Yin (Sharingan, genjutsu, Susanoo and all mangekyou) and the Senju wiht Yang (strong, versatile, good reserves and long living). The Uzumaki are a clan connected to Ashura (because Naruto) but have powers of both: Vital and long living like the Senju, but powers (e.g. Adamantine Sealing Chains, healing, sensing) like an Uchiha. I suspect they're a mixture of Indra descendants that lacked Sharingan (it's a KKG and they do not necessarily pass on) with Ashura indra. When was sealing and healing attributed to Uchiha? I don't remember it. Overall I agree with your post.

Also I don't think Uzumaki clan symbol was based on Indra's Mangekyo Sharingan, it could just be that it was based on whirpools forming there and the red colour could symbolize red hair or something, the clan might have formed after some generations.
