Rip N' Ride Combo Damage Bug? (Unsure)(PS4)

[(PSN)Singularity-X1]

So I am not sure if this is a bug or not, but during said combo for the Ghoulsaw weapon seems to not do any damage during the second phase of the attack. I tested it in the Simulacrum to make sure I wasn't imagining it and I'm running: Primed Pressure Point, Primed Reach, and Fury to ensure it's not a case of just low damage numbers or not connecting the hits. It does do damage on first contact and during the first half of the riding attack, but during the latter half of it, it seems to cease doing damage even on direct hits/driving into enemies. 

So this makes me unsure as to whether it is an intention design decision or a bug. 

Following up: So it definitely is coming off as more of a bug, at least I really hope it's just a bug. I managed to get the attack to continuously drive into a single enemy and there is no damage dealt during the second half of the riding attack. And I even drove right past the enemies, almost hitting them and there is still no damage dealt.

At first i thought that it will only work on downed enemies as to you know slice them up but it seems atleast for me doesn't work either which made me a lil sad
