Position of the logical volume on the physical volume

Hello everyone,

I just read that while creating a logical volume(LV) we can choose the region of the physical volume (PV) in which the LV should be created.
When I say region I mean: outer edge - outer middle - center - inner middle and inner edge.

Can anyone help me understand the utility of that possibility ? How can we do that ( example please) ?

Thank you
