Multiple HOD

I was watching some videos on someone playing blackheart, forgot the guys name ill get it, but anyway he caught someone in the corner with the HOD. after the first hod he did another. I think he did a total of 3 or 4 in a row. I thought I was goin crazy, but I kept watching it but couldn’t figure out how he did it. I just recently started playin bh cuz I’m tired of all the top tier teams and tryin new stuff. if anyone has any info on this crazy sh*t post it.
