trampling ox animation

excuse me if i'm really really late to this particular party, but why does trampling ox share the same animation as falling spider and falling lotus strike? visually, the assassin makes one hit, but the game registers it as two.

although i'm not completely sure about this, but i believe dual attacks have slightly longer activation times (as in, the two hits will conclude slightly slower than one hit from lead and offhands). if this is the case, then we have a dual attack that activates faster than the others, which would be a balance issue.

anyways, sorry if this has been discussed before. i've never really used this skill too much.

I always assumed that the dual attack timing was like this;

First attack *pause* second attack, for damage.
The *pause* Is where I assumed the activation time to be for lead and offhands.

And about the trampling ox animation, I honestly don't know.

The animation where you actually hit them has a delay, as in, you stay on the ground with your daggers "in" the person for longer then you do with falling spider/lotus. So no balanced issue there.
