Purpose of IsRefreshing = true also triggering command?

[ziomek64]

Hey,
Like in the title what is the exact purpose of it? If you can set IsRefreshing to true you can probably just fire the task instead of that. I was pulling my hairs out, because I didn't know that and it caused me so much issue because I had IsRefreshing to true on other commands not only the refresh one which in my case replaces the list with a new one from api. And the other tasks updated one property of one item in the list which was messed up because of that.

My question is shouldn't it only do visualization? If not, what is purpose of it?
