I saw those comments too and they got me confused.
Back when the song was released, he mentioned that it had been recorded on a smaller and simpler kit and you can notice that throughout the song too. But after the intro video he posted he is talking about differences in mics and setup ups on his home drum kit and the studio one, how this was not the kit he used to track the song and stuff like that.
So I really don't know whether the kit was actually smaller and simpler or not, or if he tracked the drums of this tune at home or at the studio. But what seems to be confirmed is that there was a 2nd kit setup in the studio sessions for DT15, which is interesting.
