You can hear snare from original tune on every 3d of a bar alongside with usual dnb snares at 2nd and 4th of a bar.
So there are 3 ways - It can be bootleg which was written in a few minutes. It can be original which was speed up up to dnb tempo and double dropped with some other tune. Or it can be an awful remix with horrible drum pattern, which i hope is not the case.
UPD: I also can be wrong on drum pattern, need better audio.
