Can kindling also happens when updosing? What are the implications?

I don't know much about this kindling effect and I am wondering about if it's possible to happen and also the implications in my current point of my taper.

Kindling happens through multiple WD's, you haven't actually withdrawn so you won't kindle

You have to totally taper to zero dose, then start the benzo over again and try to withdraw again for kindling to occur.  This is not your situation.  There are no implications in your taper.
