The green energy in her blade is definitely used to disarm the knight, as you can see it exploding in a couple of frames before those violet shards appear.

The "Violet" currently mentioned in the article is just an aftereffect, (or maybe a minor element of the spell) which happens to last long enough for people to notice it instead of the main event.

An additional detail to add is her intelligence/quick-thinking while under pressure, as the repulsion trap wouldn't have worked if the knight still had the extra range of his sword. So she either pre-planned the disarm->trap sequence or made a snap decision upon realising that it was forced to charge her with it's fists.

I've gotta say though, White is the best depiction of a swordmage I've ever seen and an all-round awesome character. Great stuff.
