Commando skill 'Gravity Well' - bug or misperception?

[Zaltiar]

Also, for gravity well, I've found out that the mobs are pulled to the position when I hit the skill button.
For example, I run to a wall, hit the skill button at the wall and walk to the opposite side, even though the skill is still "charging" since it takes about a second for the mobs to be pulled, they are still pulled to the wall where I used the skill, not to where I am exactly.
This works well as I usually follow singularity right after to push them right back to the wall. (cause if anyones ever run with me, they know I like to keep running around lol)
Can anyone else verify this?

edit: or actually it may not be "exactly" when I hit the skill button...but there is still a duration where the position they are pulled to is set.
edit 2: (lol) tested it out on a few mobs, sorry if this post has gone off main topic lol.
When using gravity well, there is a round purple "charging" sign on the commando, right when the purple charging sign goes away is where the targeted mob/mobs are pulled. That gives about 2 seconds where you are able to move around after
