Kinda hard to tell from the screenshots but if you watch the replays it's definitely inhuman. I saw rrtyui's replay before you posted this and was also confused... assumed it was just a replay glitch (had no idea about this multiple of 100bpm thing).
As for whether it's a glitch or hack on www's part I have no idea but it's definitely not how www would have timed his presses.
