I think he's milking his GS money.
It's basically the same style, everything emulated. Just a different beat, different costumes, and a different (but similar-style) dance.
All those views are from curious viewers (like you and I), coming off his 1b views GS success.
If he does it a third time, he'll be washed up.
Regardless, it's still a unique style in the music industry at present, with catchy wackiness, and hot Korean chicks.
