Is this a mech of Sin on it's own or just kara cancel shenanigans?

I mean after a contination(in this case pale driver) sometimes I get to pull off a dash into tyrant rave, using 2 stamina of course on what I think is just happening a REALLY QUICK dash-cancel-tyrant

Just asking if this is a mech of sin or is just a game kara cancel thing and how I can pull it more often in the case of both, sometimes it goes out and sometimes it doesn't
