For a long time, we knew that the elder son had a spiral Rinnegan. In the last chapter, however, it was revealed he had a normal Sharingan. Now originally, the idea of Spiral Rinnegan made sense, for these reasons:
1. If the elder son had a Spiral Rinnegan, than the original Rinnegan obviously degraded over a single generation. This meant that future generations experienced even more degraded versions, eventually leading to the Sharingan.
2. If the degradation theory was correct, than spiral Rinnegan makes for a fitting transition stage.
However, this theory had essential problems to it:
1. If the Rinnegan took multiple generations to become sharingan, than the sage or the elder son might not have lived to see the Sharingan in existence.
2. If neither of them ever saw it, how could they write a tablet explaining how to progress it back to Rinnegan?
With it now known Indra had Sharingan, it solves this essential problem:
1. Indra obviously found some way to progress the sharingan to Rinnegan, starting with the MS. He could have easily obtained MS by emotionally reacting to his brother's sudden rise in power. As long as he gained access to EMS after that, he could get Rinnegan.
2. The sage's brother might have had sharingan-using offspring or perhaps the elder son had sons of his own with sharingan. Either way, there is enough possible people involved to create one or more pairs of EMS.
3. Indra finding a way to get the full Rinnegan would explain how and why the tablet describes methods for achieving Rinnegan from a base Sharingan.
To summarize, I feel that the elder son possibly NEVER HAD SPIRAL RINNEGAN TO BEGIN WITH, KISHI LIKELY OMMITED IT FROM HIS MANGA ENTIRELY. Not having Spiral Rinnegan actually makes better sense to the story since Rinngan progression goes straight from EMS to Rinnegan, with no Spiral Rinnegan stage. Indra having Sharingan actually explains how the tablet could have been written explaining how to progress Sharingan to Rinnegan within the Sage's and the elder son's lifetime. Indra's potential offspring or even the sage's brother's offspring could have provided the means to one or more pairs of EMS down the line. Indra could have easily achieved MS through emotions suffered from seeing his weak brother progress to his level in such a short span of time.
Edit: Further proof the spiral might never have existed (credit to Vergilius for this one):
Obviously back when the Spiral Rinnegan was shown, we didn't know that the Sharingan could indeed become Rinnegan. So what Kishi was likely doing with that panel was showing us that the elder son had a DIFFERENT doujutsu than his father. He simply wanted to show the difference between his and his father's eyes but did not yet want to reveal it was Sharingan. Again, just more proof that the spiral Rinnegan perhaps never existed in the first place.
