I don't see it as different behaviour, I just see it as her not having developed a good schtick at this point, so she needs to use more physical provocations.
Well, we don't actually see it at all, because they don't show that behavior.
But,, psychologically speaking, it would be markedly different behavior.
If she goads and humiliates until someone attacks, that allows a lot of rationalization - if they use normally deadly violence as a response to mere words, they aren't all that great people themselves, so they sort of deserve what they get.
If she actually starts the fight, then she is actually the aggressor, a thug waylaying them for their power, and she's just committing murder.
