Why pull-to-refresh indicator again come from top rather than stick on offset

Question

What is the reason the pull-to-refresh indicator appears at the top of the screen when navigating back, instead of sticking to the previous offset position while still refreshing it is coming again from top, is primarily due to how the PullRefreshIndicator and the pullRefresh modifier are implemented in Jetpack Compose.

Note: Carefully watch indicator in the last that is slightly coming from top to it's offset.
