Sawari questioning

So I watched Kyles video on sawari, what it is and how do do it.

My question is that is the sawari effect suppose to be heard only when playing open strings or can it be heard when playing positions?

Can someone assist me with my question?

Hi! Basically you should hear it when playing open strings as well as certain positions. Especially when playing octaves it is very noticable. Like the 10th position on the highest string for example.
