Yes it appears he used Chidori to Damage Madara, since that was the case most of the time when sealing jutsu was used , every time some one had to strike down opponent in order for some one else to seal it.

Yet he used that same hand to seal Kaguya. But he didn't form chidori or anything, just made contact with her.
