Attack triggers being wonky

I noticed a couple of things playing the hell knight. I got the enduring rage perk, and with the asura heartripper I was anticipating it to act like it got the attack command twice (one set of four hits followed by a second set of four) is it intentional that it only adds one more hit? So 1 set of 5?

And I fused my unicorn vivifier with a unicorn consicrator and I can trigger a revive but I don’t get a heal (my other creatures were already damaged so it was easy to notice something amiss)
