I mean, the "how" doesn't seem far off, if she's a fast typer or even uses some macros or code.
The "why" is a bit more stretchy, since that whole schtick is a pretty planned and collected sort of "crazy", like Batman's Joker. Which isn't really crazy per se, and thus doesn't gel with the Malk theme quite so well, in my opinion. But she could be an outlier, and Malks aren't perhaps a monolith like that, etc., I don't know enough of VtM to really judge.
tl,dr: I get where you're coming from, and it was a bit off for me as well, but I don't think it's really gamebreaking-tier.
