Saying he was the true creator of the Chidori is not technically correct. Yes. While he was the first to create the practice of using hand signs to initiate Jutsu, he didn't create it. Kakashi was the original "inventor" of the Chidori, which was basically him trying to add Lightning Release to the Rasengan, but it failed and burst out. While Chidori did look like the Lightning Release Jutsu Indra had used, we can assume that it was a whole different Jutsu in regard.

Also take note that the Rasengan, which Kakashi tried to add on to, was an invention by Minato, the 4th Hokage himself. During the time of Hagoromo, since his mother was the first Chakra user of all time, he was already gifted with amazing Chakra control. His sons later on, also gained the Chakra infinity... actually not true. Asura was the prodigy, but not Indra. Asura then "created" the original Rasengan, or rather something that Minato would take and master it into the Rasengan. Indra would probably have no idea about it, and therefore wouldn't know how to use it.

To make simply. Chidori = Rasengan + Lightning Release. Indra did not know Rasengan or the technique his brother created. So no. Indra was not using a technique that predecessors the Chidori in anyway.
