It never says anything as to when, comparatively on a time line, the following events happen(order means nothing):

Riven gets her blade.

Noxus attacks Ionia.

Riven becomes an exile.

For all we know she could've learned the technique before even ever coming close to Ionia, but the technique could've been something she personally adapted to her liking from her master. I'll assume Ionia is the source of most classical swordsman dueling, so its likely their styles are adapted in other regions (at war or not) and can be seen elsewhere in different forms.

Riven's wind technique could be like the American English of Yasuo's technique (old British English).
