Pausing as if

[Maybo]

Chelsea gently lays the blanket over his lower body, pausing as if not sure if she should put it over his head or not. Finally, she covers his face too, turning her boyfriend into nothing more than a darkening lump on the front porch.

I sometimes see this sentence pattern: …, verb+ing…
I’m not sure if I understand the functions of that sentence structure correctly.

1. Chelsea gently lays the blanket over his lower body, pausing as if not sure if she should put it over his head or not.
(While Chelsea lays the blanket, she pauses)

2. Finally, she covers his face too, turning her boyfriend into nothing more than a darkening lump on the front porch.
(The covering of her boyfriend’s face turns her boyfriend into a lump)

#1 is showing that someone is doing A while doing B at the same time.
#2 is showing one action is causing a result.

Have I got that right?

I wouldn't say that she pauses "while" putting the blanket on her boyfriend. She put the blanket on his lower body. She paused for thought. After that, she decided to put it over his head.

When somebody pauses they are not doing anything -- nothing that you can see anyhow.
